Installation

In rare cases, it may happen that SIMARIS design or SIMARIS project cannot be started after setup and an error message will be displayed indicating that Java cannot be started.

 

During the starting phase of Java, 768MB of non-fragmented memory space must be available. If not, for example, because the memory is used up by other programs, the above error message will be triggered. 


To remedy the problem, please execute the enclosed patch. To do so, download the ZIP file, decompress it and then start the ResetMemory.exe file. Here it is important that the file is executed with administrator rights. Depending on which program causes the problem, choose SIMARIS design and/or SIMARIS project. Click "Install".

 

The requirement for available memory is reduced to 512 MB. SIMARIS design, or respectively SIMARIS project, can then be started without any problems, however, the programs will perhaps work a bit more slowly, since they now use or have available less RAM.

Please find the system requirements for download by clicking here.

Please find the system requirements for download by clicking here.

A "network installation" is intended for use in a centrally administered computer network. In contrast to a local installation, SIMARIS design or SIMARIS curves cannot be updated online in this case.

 

However, all updates are also provided for download as installation packages at www.siemens.com/simaris/update. The respective installation package includes all previous hotfixes and updates referred to the last main version.

 

To update a network installation of SIMARIS design or SIMARIS curves using the installation package (offline update), please proceed as follows:

  1. Download the ZIP file containing the service pack.

  2. Decompress the ZIP file and save the .exe file on the server.

  3. Run/Install the offline update by starting the .exe file.

In a network installation, the settings made by users and the Favourites saved by them are stored in a Roaming Profile, thus being available to all computers in the network, whereas a local installation just saves this data locally on the user’s computer.

As a rule, the SIMARIS planning tools can only be executed under a Windows 7, Windows 8 or Windows 10 OS, as described in the system requirements for SIMARIS design und SIMARIS project. In order to be able to use the SIMARIS planning tools on a Mc PC or MacBook, you must install a virtual machine with a Windows operating system. With the aid of this system, you can then install the SIMARIS planning tools. However, Siemens does not render any support for such systems, because only setups under a Windows 7, Windows 8 or Windows 10 OS are supported - as described in the system requirements.

In case of the SIMARIS design 9.0.1 has been installed as “network installation”, an update to SIMARIS design 9.1 might not be executed correctly and the version number does not change.

 

To remedy the problem, please execute the enclosed patch. To do so, download the ZIP file, decompress it and then start the Patch_SIMARIS_design_9_network.exe file. Here it is important that the file is executed with administrator rights. Please select the installation path and click “install”. Afterwards the update can be executed as usual.

 

Patch and Update can be executed via script as well.

Registration

The latest generation of the SIMARIS software tools is available in the following versions with the corresponding registration routines:

  • SIMARIS design
    Registration: There is a 20 days (usage days not calendar days!) evaluation period after which you will need to register in order to use SIMARIS design without any temporal limit.
    If you have already installed SIMARIS design in the evaluation mode, you need to enter your data for registration on our website. The page is automatically accessed when you click “Register” on the start screen of SIMARIS design. Your data is required to generate your license file, which must be imported when starting the software.

  • SIMARIS design professional
    Registration of SIMARIS design professional is absolutely necessary to enable the special functions of the “professional” version. It requires an authorization code which you can find on the "Certificate of License". This certificate is included when you order the software with a floating license from your consultant promoter against a nominal charge. Please enter this authorization code in the field "Authorization code" in the form on the website. If this field is not filled in, a license file will be generated which will, however, not enable the special functions of the "professional" version of SIMARIS design.

  • SIMARIS project
    Registration works the same way as for SIMARIS design.

  • SIMARIS curves
    Registration is not required.

Registered users of SIMARIS will automatically be informed about the latest versions. Furthermore, a registration is needed to enable Siemens AG to provide you with ongoing support. All of your data will, of course, be treated confidentially.

The registration of SIMARIS design and SIMARIS project is free of charge.

 

The registration of SIMARIS design professional can be performed after purchasing the license by entering the respective authorization code in the registration form. If you are interested in SIMARIS design professional, please contact your local SIMARIS contact partner.

In case you have lost your license file for SIMARIS design 9 or SIMARIS project 5, please get in touch with your local SIMARIS contact or just feel free to register again. Any new registration will also be free of charge.

 

If you have lost your license file for SIMARIS design 9 professional, please get in touch with your local SIMARIS contact. He/she will assist you in getting a new license file.

The most probable reason for this is that you still work with an out-dated SIMARIS design release (4, 5, 6, 7 or 8) or an out-dated SIMARIS project release (1, 2, 3 or 4). We kindly ask you to download SIMARIS design 9 and/or SIMARIS project 5.1 here.

 

Furthermore under certain conditions within Windows 7 (e.g. virtual store deactivated) it may happen that the license key cannot be imported directly, but only can be imported when the software is executed “as administrator”.

 

To do so, please position the mouse cursor on the program icon (Desktop) or on the start file (Explorer) and start the program from the context menu which you can call up using the right mouse button and select "Run as administrator".

 

Another reason could be that you confounded the license files for SIMARIS design and SIMARIS project. The names of the licence files start with the following letters and differ in their file extensions as follows:

SIMARIS design
Sd_key....lic-sd
SIMARIS design professional
Sd_pro_key....lic-sd
SIMARIS project
Sp_key....lic-sp

If you import the licence file for SIMARIS design or SIMARIS project when being logged in as administrator, a licence query will still be displayed upon start of SIMARIS design or SIMARIS project, when another user without admin rights executes the program.

 

The reason for this issue is the permissions concept of Windows 7. Even an administrator does not automatically have write permission in the programs directory any more. This is however strictly required for importing the licence file.

 

To import the licence file for all users, please proceed as follows:

  1. Log in as administrator

  2. Go to the program directory of SIMARIS design or SIMARIS project

  3. Right-click SIMARISdesign.exe or SIMARISproject.exe -> Select "Run as Administrator"

  4. When being prompted whether the program may be authorized to perform changes, confirm this question by clicking "Yes"

  5. Import the licence file

This licenses SIMARIS design or SIMARIS project for all users and enables them to execute these programs without being granted special permissions.

A country-specific technology package contains devices which are available in the respective country and comply with the applicable standards and accepted rules of good installation practice of that country.

 

During the setup process of SIMARIS project, you can select those countries relevant to you from a list. This selection also installs the corresponding technology packages of the selected countries. If no country was selected during setup, no technology package will be installed either, so that the above message will be displayed.

 

But you can always install the technology packages you need later, by restarting the setup process of SIMARIS project and selecting the desired countries in this new setup process.

Update/Hotfix

Such problems do not originate in the SIMARIS software tools, but in the JRE included, which is always kept in the "jre" folder in the setup directory of the installed programs. This folder cannot be updated online. However, users can manually copy an up-to-date JRE into this folder. Another possibility is to delete the "jre" folder completely so that the programs will then draw on the Java version installed on your computer. However, these changes in the setup of the SIMARIS software have not been tested by Siemens.

In order to be able to offer an optimal service and address feedback from our customers, we provide updates and hotfixes that enable you to keep your software always up-to-date. We strongly recommend the installation of the offered updates and hotfixes.

You can find our latest updates and hotfixes respectively here.

 

You will need administrator rights in order to install this update and hotfix respectively. SIMARIS design should not run, when the update and hotfix respectively is being installed.

When a user runs an online update of SIMARIS design or SIMARIS project, at first it seems as if it was carried out correctly. But the program displays the previous version status after restart (Help menu > Info…).

The reason is the user authorisation concept of Windows 7. This prevents the proper update of program components by an online update if the program is executed with normal user rights.

 

To perform the update, please proceed as follows:

  1. Exit the program.

  2. Log in as Administrator.

  3. Start SIMARIS design or SIMARIS project "as Administrator": Right-click the shortcut on your desktop or SIMARIS design.exe or SIMARISproject.exe in the install root > Select “Run as Administrator”.

  4. Run the online update.

  5. Exit SIMARIS design or SIMARIS project.

  6. Restart the program with your normal user rights.

Other

For technical support and troubleshooting get in touch with your local SIMARIS contact.

For projects done with version 4.0, 4.1, 5, 6, 7 and 8 this is possible. Due to the new structure, user interface and handling this is not possible for projects generated with SIMARIS design V1.5.

The demo project for SIMARIS design and SIMARIS project can be loaded every time you open the software by selecting this option in the first window which opens automatically.

 

If you have already closed this window, you can find the demo project for SIMARIS design in the selected path for installation in the folder: 
C:\Program Files\Siemens\SIMARIS design 9\plugins\com.siemens.simaris.design.resources_1.3.2\Projects\Templates

 

File name: Demo_SD9.sd // Demo SD9prof.sd

 

For SIMARIS project you can find the demo project using the "Help" menu > Open Demo Project.

Dimensioning

Depending on the place of installation and the rated current of the power consumer, the relevant standards require additional protection by RCDs.

 

When choosing a “place of installation”, please observe the detailed explanations given in standards (IEC 60364-4-41 or DIN VDE 0100-410, DIN VDE 0100-701, IEC 60364-7-702) and the exceptions described there in addition to the excerpts from standards as quoted below.

  • Outer zone (outdoors): RCDs are obligatory for final circuits of portable equipment used outdoors up to an equipment load current of 32 A.

  • Wet zone (= rooms containing a bathtub or shower): all circuits must be protected by one or more than one RCD with a rated residual current of max. 30 mA.

  • Inner zone (indoors): RCDs are obligatory for socket-outlets with a rated max. current not exceeding 20 A, which are intended to be used by unskilled, ordinary users and for general-purpose applications.

You can have your entire network or partial networks and individual circuits automatically dimensioned by SIMARIS design. For an optimized dimensioning result, only the operating modes and switch settings freely pre-defined by you are considered for calculation and device selection. SIMARIS design calculates the minimum and maximum short-circuit current from all pre-defined operating modes as a basis for the entire network dimensioning.

Certain circuits are not included in the automatic dimensioning cycle, although the corresponding operating modes for supply were set. I get unexplicable error messages which canot be eliminated. When I call up the quick view for the calculation results ("Tooltip") "Circuit was never closed or supplied" is displayed. This occurs with circuits which I cannot even connect into, or disconnect from supply in the Operating modes dialog.

 

These circuits are internally disconnected, although they are designed as non-switchable in the Operating modes dialog. Proceed as follows in order to restore the calculation: For individual circuits (loads, directional couplings), delete these circuits and add them again. If larger subnetworks are affected, please create a new infeed (this is only possible with SIMARIS design professional) and then move the affected subnetwork to the infeed's LVMD. Then redimension this new network automatically and move the affected subnetwork back to its original position. Finally, you can delete the infeed which you created. If this method is not successful, please contact your regional SIMARIS representative.

SIMARIS design only lists the most common transformers with vector groups Dyn1, Dyn5 and Dyn11.

 

Calculations in SIMARIS design that concern transformer vector groups only use the resistance ratios R0/R1 and reactance ratios X0/X1.

 

But if the use of other transformers is required, it is possible to specify the impedances or loop impedances of the feed-in system. This equivalent circuit mapping renders an accurate calculation.

Handling of the Software

The circuit must be selected with a mouse click. A Copy action can be performed in the following ways:

  1. Press the key combination CTRL+C (Copy) and then CTRL+V (Paste)

  2. Use the relevant commands which are displayed with a right mouse click

  3. Use the Copy/Paste buttons below the menu bar

  4. Make an appropriate selection in the Edit menu

This information cannot be printed directly. Instead it can be copied and pasted into a suitable document (e.g. Microsoft Word), which can then be printed. To do so, first click any point in the quick view of calculation results (don't select anything) and use the key combination CTRL+C to copy the data on display. The data can be included in the target document with the usual Paste options.

In the graphic display of the network diagram, every added load means that the displayed busbar (blue line) gets wider and wider. It may happen that the busbar cannot be represented any more on the paper size you have chosen, or that the busbar view gets confusing.

 

To divide the busbar in the graphic display, and thus facilitating a clear layout of the network diagram within the selected paper size, the busbar can be divided with the help of the Library element "Group switch".

 

This means, as soon as the busbar has reached near paper width, or depending which subdivision of the load groups seems reasonable, one or more group switches will be added to the busbar. When making specifications for the group switch (in the window which opens after adding the switch to the network diagram) it is important to select "None" as type of switchgear, both for the upper and lower switching device. For reasons of transparency in the project documentation, such load groups may be assigned the same name as the upstream distribution system. These groups can be moved or rotated in the graphic view according to project needs.

 

Compared to a through-busbar, this group formation by way of the graphically inserted group switch (but without switching device!) has neither an effect on calculation/dimensioning in SIMARIS design nor on the export for SIMARIS project.

 

The two project examples each show a distribution system, one without and one with a division into load groups using a group switch.

Coupling

A "normal coupling" means a coupling where the direction of energy flow between the busbar sections is not defined. A directional coupling, however, means that the direction of energy flow between the busbar sections is defined. It can be used for mapping combinations of normal and safety power supply (e.g. between transformer and generator networks). The coupling is designed in compliance with IEC 60364-6.

In order to add a directional coupling with a defined direction of energy flow that maps an emergency network, the cursor must be placed at one of the inner insert points of the busbar of the infeed circuit (i.e. not at its end), after the icon for adding a coupling has been enabled.

 

In order to add a normal coupling with an undefined direction of energy flow that maps a normal power supply network, the cursor must be placed on one of the insert points at the outer ends of the busbar shown for the infeed circuit.

 

The following input dialog for the selection of an infeed which is connected to the network through the coupling provides the option to select identical types of infeed or different ones.

A directional coupling is a changeover unit for supplying safety-relevant consumers. These units require in compliance with DIN VDE 0100 - 710 (IEC 60364-7-710, modified) section 710.537.6.1 that the tie breaker is installed in the main distribution board of the safety power supply system. In compliance with DIN VDE 0100-430 (IEC 60364-4-43), the switch at the beginning of of this changeover unit serves for the short-circuit protection of this connection between the normal distribution system and the distribution system for safety power supply.

Active switchover takes place at the infeed level, passive switchover takes place at the sub-distribution level.

Medium Voltage

When an infeed line with medium voltage is chosen, dimensioning is also performed for the fuse/circuit-breaker upstream of the transformer and the associated cable.

Transformers and generators can be mapped in a voltage range of 3 to 40.5 kV. Dimensioning is performed automatically for the integrated default values which can be selected from the drop-down menu in the Properties window. In case your project requires specific power ratings or voltages, you can enter these values manually. To do so, select the transformer/generator in the network diagram, right-click your selection to call up the Properties dialog and change the "Manufacturer" data field to "Any entry" so that you can then enter the technical data as desired.

It must be kept in mind that this is a combination of switchgear and protective device. To this end Simaris design contains a specific type of switchgear (8DJH).  Protection is rated dependent on the selected switchgear. Different protective devices may also be chosen manually. Proper implementation in practice is up to the planning engineer, whose responsibility is emphasized accordingly in the software.

With regard to the medium voltage level, SIMARIS design only dimensions the transformer outgoing feeders. These feeders are also included in the selectivity evaluation.

Circuit-breaker type L1.1: vacuum circuit-breaker, SI-capable, Ir = 10,000 / M2, ISC = 25 or 50

 

Circuit-breaker type L2:  vacuum circuit-breaker, not SI-capable, Ir = 2,000 / M1, ISC = 6 or 20

 

Legend: SI = short interruption; Ir = number of interruptions (break operations); ISC = number of short-circuit interruptions

Motors/Motor Starters

Using simple motor protection in the planning process ensures cable protection provided that no other details are known about the motor starter combination.

At present, circuit-breaker-protected and fuse-protected motor starter combinations have been integrated in SIMARIS design. These are tested assemblies according to CA01. Motor starter selection is restricted in terms of voltage to 690 V maximum and in terms of power rating to 250 kW maximum (depending on the selected voltage).

Since the motor starter combinations kept in the database are tested combinations, they are selected automatically in SIMARIS design on the basis of the selected motor power.

 

If a suitable combination cannot be found in the first step, you have the possibility to use one of the following tables to find out which of the design-tested combinations provided is best suited for your project requirements. After this selection has been made, you can then adjust the data to be selected for this combination in SIMARIS design (type of construction, starting type, coordination type, overload relay and, if applicable, motor power), so that the desired combination can be considered in your planning.

 

The following tables present an overview of the motor starter combinations kept in SIMARIS design:

Network Parameters

The rated current is the basic device value. The permissible current is the value which is affected by the ambient temperature of the device. For example, the rated current is 125 A at an ambient temperature of 60°C, whereas the permissible current is only 116.25A.

Simultaneity factor gi
The ratio of outputs of all simultaneously operated consumers to the rated outputs of all connected consumers. The simultaneity factor (for distribution boards only) is directly incorporated into network dimensioning (cable cross sections, protective devices, transformer size).

 

Capacity factor ai (for motors only)
The motor capacity factor indicates to which proportion of the rated motor power the motor loads the network. The capacity factor has no impact on the dimensioning of cables and protective devices for the motor circuit. The motor circuit is designed for the nominal motor current. The capacity factor is incorporated into the dimensioning of the higher-level network (cable cross section, protective devices, transformer size).

At first you do have default values for medium and low voltage. If you change them once when working on a project, these changed values are retained when you open a new project in Simaris design.

Busbars

The busbar systems used in the project configuration will be tested for thermal short-circuit strength and overload protection. Dynamic short-circuit strength is present if both attributes are fulfilled (see IEC 60364-4-43 Clause 434). Dynamic short-circuit strength is not verified directly.

Providing that this busbar is used for power distribution, the busbar type cannot be changed in an existing project configuration, since there are different tap-off units for all busbar types. Changing the busbar type would thus inevitably result in error messages being returned. If these busbars are used for power transmission only, busbar systems may be altered at any time or you may even replace busbars by cables.

As a rule, LRC busbar systems are strictly intended for power transmission only. This is why SIMARIS design only reproduces this kind of application.

No, this option is not provided, since busbar systems must be individually chosen and rated for every project depending on the architecture and intended area of application. The info window, which can be displayed when selecting busbar systems, contains all information relevant for selection. Users must then make their choice themselves based on the prevailing conditions known to them and the information provided for a specific busbar system.

Selectivity

In SIMARIS design, the selectivity interval is the minimum interval between the rated current of the downstream and the upstream connected device. Possible input values for the selectivity interval are between 1 and 3.

 

Example
Condition: The dimensioning target is selectivity and the selectivity interval is 1.55. Downstream there is a fuse with a current rating of In = 100A. SIMARIS design dimensions an upstream connected protective device with a minimum of 155A, although such a high rated current might not be needed.

Selectivity evaluation is only available in SIMARIS design professional.

 

If selectivity evaluation is enabled by clicking the corresponding icon on the tool bar above the network diagram, all switching devices on the network diagram will be highlighted by a green, yellow, or grey colour field.

  • green: item is fully selective

  • yellow: item is partially selective

  • grey: item cannot be evaluated

This can be interpreted as follows: The behaviour of device combinations regarding selectivity can only be established by testing. For those combinations marked as fully or partially selective, appropriate testing is available, but not for the items marked in grey.

Other

To obtain an overview of these additional functions, please click here.

A list of the key combinations available in SIMARIS design can be called up in the software using the menu item "Help" > "Key combinations".

Transformers and generators can be mapped in a voltage range of 3 to 40.5 kV. Other third-party equipment cannot be defined or mapped, since verified data of all device combinations applied must be available for the purpose of protective design and selectivity evaluation.

When adding a dummy load, no switching devices or cables/wires are dimensioned within this circuit, but the load still influences the energy balance.

Printer management regarding this problem is not integrated in SIMARIS design itself. Generally, project output of SIMARIS design is created in DIN A4 format (letter size) with the exception of the network diagram in PDF format. For this file type, users may choose the (original) paper size (max. DIN A0 or any paper size) when editing the network diagram.

 

During Project step 3 - Project Output, PDF file output is then governed by the printer-specific menu and can usually be adjusted as desired from there (compressed to one page, distributed to several pages in original format etc.). The functionality of the printer menu and its operation depends on the actual hardware (printer) and must be handled accordingly.

If 800 mm² was set as maximum cable cross section in the technical settings for low voltage in the “Project Definition” program step, the value that can be selected in the “Network Design” program step depends on other settings additionally defined in the cables/wires properties:

  • Selection of the conductor material: aluminium (the max. cross section of copper cables/wires is 630 mm²)

  • Cable type: single-core cables

  • Selection of installation type: F bundled, F row, G horizontal or G vertical (can only be selected by clicking the i-button near the “Installation type” drop-down box)

If a value less than 800 mm² was already set as maximum cross section in the technical settings for low voltage, despite the other settings made as listed above, the value permitted for selection in the “Network Design” step will be lower in proportion.

When you use SIMARIS design for your project design, you can also consider disconnectors without protective features. They can either be selected when the relevant circuits are created, or they can later be added, when the circuit properties are edited. To do so, the corresponding switching device is selected on the network diagram, so that an appropriate switch (disconnector) can be selected in the Properties section shown below the network diagram on the left.

 

Since disconnectors do not affect circuit protection or short-circuit protection, they will only be checked for their current carrying capacity and short-circuit strength.

 

This means that the selectivity diagram will not show any characteristic curves for these devices in the selectivity evaluation routine of SIMARIS design professional. And consequently, there is no colour coding referring to full/partial selectivity on the network diagram either.

To show a legend containing all symbols in SIMARIS design you can download the respective drawing frames. Afterwards you can load them into the program via software menu "Tools" - "Settings" - "Drawing border" and activate them subsequently at "View" - "Papersize" - "Reload frame".

Plants

In SIMARIS project, you can map a network comprising about 22 cubicles of low-voltage switchgear if 1GB of RAM is available on your computer, or a network with 30 cubicles in case of 2GB RAM. This information refers to a project, i.e. the cubicles contained in several low-voltage switchgear units within the same project add up. This development is not linear, any further RAM increase does not result in more cubicles being processed. This is due to MS Windows constraints.

 

In order to increase the allocation of RAM in the software, please set the requirement for the maximum RAM in the "SIMARISproject.ini" file to a higher value. You will find the "SIMARISproject.ini" file in the “Sp2.0” root directory of your SIMARIS software installation. In "SIMARISproject.ini", please change the entry "-Xmx768m" to "-Xmx1024m". This increases the RAM from the default value of 768MB to 1024MB.

 

If you would like to import larger networks from SIMARIS design, we recommend that you split the network in two parts. If necessary, you can then add the missing coupling in SIMARIS project.

 

Regarding other plants (medium voltage sections, transformers, busbar systems, distribution boards), there is no restriction as to build up any number of plants comprising any number of cubicles/panels within a project.
