Revision as of 13:08, 27 September 2023

Application Details

• Description: Produced by Siemens CD-adapco (Computational Dynamics-Analysis & Design Application Company Ltd), star-ccm+ is used for computer-aided engineering, in particular, computational fluid dynamics (CFD).
• Versions : 15.02.009 ( + R8) and starccm+/18.04.009.R8

• Module names : starccm+/15.02.009 (and starccm+/15.02.009.R8) and starccm+/18.04.009.R8
• License: University of Hull Engineering department, restricted by POD license.

Important information

• Important: where possible it is recommended to use versions 18.04.009 and 15.02.009, versions 13/14 will be retired soon.
• The SIM data processed should be the same version of the star-ccm+ application, there is a strong sensitivity in this program.
• Multiple node processing will need the addition of the file in $HOME/.ssh/config (with StrictHostKeyChecking no)

Usage Examples

Batch Submission

Up to Version 15

Interactive

Although the recommended method is a batch session it is also possible to run this as an interactive session. While logged into a compute node (c143):

Star-ccm server

Star-ccm+ can be used as a server within an interactive session on Viper. This would be very useful for graphics from big simulations.

• Check SSH keys are been generated correctly for this version of SSH.

Known Issues

• After version 13; no noted MPI issues.
