Question

How do I create minimal installations for running Simcenter Amesim FMUs or other exported models?

Answer

Overview:

Simcenter Amesim provides scripts to create lightweight minimal installation packages for running various kinds of exported Simcenter Amesim models (for instance FMUs) in other software environments. After running these scripts, you can distribute the resulting installation packages along with your exported models to perform the coupled simulation with no need for full installations of Simcenter Amesim on end-users’ machines.

The current list of companion tools (or export interfaces) for which these minimal installations can be used is:

• Adams

• LMS Virtual.Lab Motion

• Simcenter 3D Motion

• RecurDyn

• NI LabVIEW (Model-in-the-Loop mode)

• NI VeriStand (Model-in-the-Loop mode)

• Any tool capable of running a Simcenter Amesim UserCosim DLL (or shared object)

• Any FMI compatible importing tool

Minimal installation generation:

The following commands will generate an archive containing the files required for running your exported models.

• To call the script under Windows, the following command lines need to be used: Copycd %AME%\misc create_minimal_install.bat <output_dir>

• From a Linux terminal, the command line is: $AME/misc/create_minimal_install.sh <output_dir>

In the above commands, the <output_dir> option allows specifying the name (full path) of the directory where the minimal installation package will be generated. On Windows the directory is created, but no archive will be generated. It is up to the user to use his preferred archiver to create the archive. On Linux the standard combination tar/gz is used.

By default the script will generate an archive of about 50 Mb that includes all the data files normally provided in a standard Simcenter Amesim distribution.

A -nodata option is available to create an archive with none of the data files mentioned above. This is especially suitable for FMUs generated with the “embed tables” option active (default setting) that normally don’t need any of these data files. In this case, the resulting archive’s size will be about 5-10 Mb. The package can therefore be conveniently sent via email.

• Under Windows, the command lines to be used are: Copycd %AME%\misc create_minimal_install.bat -nodata <output_dir>

• Under Linux, the command line to be used is: $AME/misc/create_minimal_install.sh -nodata <output_dir>

Note

The generated archives will not include any license file. Thus it might be necessary to set the licensing-related environment variables on each end user’s machine.
