1D3D Coupling GT-Power/StarCD -- CFD Online Discussion Forums

Hubert Janocha Guest Posts: n/a	I want to couple GT-Power and StarCD (GT 6.0.0 StarCD v3150A or GT 6.1.0 StarCD v3.24) on an Opteron-Cluster with mpich. For this I had to find out that SuSE SLES 8.0 is not a good choice for GT as StarCD has no problems on it. I tried RedHat ELWS 3.0. My compiler Absoft 9.0 for AMD x86_64 refuses to compile as with SLES it was no problem belonging to Star. Additionally to this when I compile and link it on a quit normal PC (RedHat 7.3 x86) and copy the whole case to the Opteron, the case runs coupled GT/Star, but only in single CPU mode. In case of SMP or distributed memory I got an mpich error (error_p4 eror_shmem). That's confusing, because when I wnat to run a quit normal parallel StarCD case in parallel every thing is OK. Is there anyone who has experience in coupling GT and Star an an Opteron Cluster? Which OS, Compiler, MPICH should I use? Thanks in awaiting your reply. Hubert Janocha
