Revision as of 11:22, 16 November 2022

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 : 13.04.011, 13.06.011,14.02.012( + R8) and 15.02.009 ( + R8)

• Module names : starccm+/13.04.011, starccm+/13.06.011, starccm+/14.02.012 (and starccm+/14.02.012.R8) and starccm+/15.02.009 (and starccm+/15.02.009.R8)
• License: University of Hull Engineering department, restricted by POD license.

Important information

• Important: where possible it is recommended to use versions 15.02.009 and 14.02.012, version 11/12 is now retired and 13 will be 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)

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):

[username@login01]$ interactive

[username@c143 ~]$ module add starccm+/15.02.009
[username@c143 ~]$ module add openmpi/3.0.0/gcc-7.3.0

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.
