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

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.
