Twix00r is on a distinguished road
Hi,
I m a student in cfd and new in this forum. Those last weeks, I have tried to handle Open Foam in order to run a submarine simulation. For that purpose I use snappyHex and found out that I could use both mpirun or foamjob to run my case in parallel. I ve made some research on google and in the forum but I can t really understand what are the differences and benefits by using one or the other ? Actually, I don t really understand what are mpirun and foamjob for OPenFoam...
Hope you can help me,
thank you
