VMoveCST is a batch utility that is used to generate CAX files from CST Studio input and result files.

System Requirements

The recommended minimum configuration to install VMoveCST is provided below.

  1. Intel Core i5 processor

  2. 8 GB RAM

  3. 256 GB Hard disk

  4. 64-bit Windows 7


By default, VMoveCST is installed in ‘C:\Program Files\VCollab\VMoveCST64’ folder

License Requirements

User can execute the VMoveCST application only if he has the VCollab “VMoveCST” license. A node-locked license can be installed by copying the license file to “C:\Program Files\VCollab\License” (Assuming that VMoveCST is installed into the “C:\Program Files\VCollab\VMoveCST64” folder). Alternately, user can define VE3D_LICENSE_FILE environment variable to provide the license file path or the server and port information

Application Usage

Its usage is as described below.

VMoveCST.bat <CST_GEX_file> [CAX_file]

The first argument of the VMoveCST is the .gex file. The results files are automatically taken from the input folder. VMoveCST generates a CAX file with the same name of the .gex file in the same folder, if CAX file is not provided. For example,

C:\Program Files\VCollab\VMoveCST64\VMoveCST.exe “D:\Models\CST\Circuit Breaker Tutorial\Result\model.gex”

The above command reads CST model from model.gex file from the given folder. It then reads the results (.m3t) from the same folder. Here, the model.cax is created in the ‘D:\Models\CST\Circuit Breaker Tutorial\Result’ folder

C:\Program Files\VCollab\VMoveCST64\VMoveCST.exe “D:\Models\CST\Circuit Breaker Tutorial\Result\model.gex” “D:\models\cax\model.cax”

Here, the cax file is created in the given folder.


VMoveCST.bat is located in the installation directory

Supported functions

  • All parts from CST Model are extracted and stored in CAX. Tetrahedron meshes are only supported in this version

  • Product Hierarchy of CST model is maintained in CAX

  • All results from .m3t files are brought into CAX

  • Generated CAX files contain no volume data.

Log File

VMoveCST generates log files during each translation. Users can find the following log files after each VMoveCST run.


The above file is written in a folder of the following format


That is, VMoveCST creates a folder in the above format for each instance and writes the log files into the folder. The folder with log files is generally written into a folder represented by VCOLLAB_TEMP_PATH environment variable. In the case of the non-existence of VCOLLAB_TEMP_PATH, the log files folder is written into %TEMP% folder.

In case of errors during the VMoveCST usage, the users are requested to communicate the errors along with these log file generated by VMoveCST to VCollab support (support@vcollab.com). The log file is designed to help the VCollab development and support teams understand the issues better and faster and provide fixes or workarounds to the user.
