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 : 12.04.011, 12.06.011, 13.04.011, 13.06.011 and 14.02.012
- Module names : starccm+/12.04.011, starccm+/12.06.011 and starccm+/13.04.011, starccm+/13.06.011 and starccm+/14.02.012 (and starccm+/14.02.012.R8)
- License: University of Hull Engineering department, restricted by POD license.
Important information
- Important: where possible it is recommended to use version 14.02.021 and 13.06.011, version 11/12 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)

Interactive
Although the recommended method as 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 correct for this version SSH
Known Issues
- It would appear that this application does not scale across multi nodes on versions 11 and 12, although version 13 does with the openMPI module also loaded.
