Hi Dear Foamers,
I am working on a propeller to simulate by different sliding mesh methods AMI,GGI and MRF.
I generated mesh by pointwise and run it on OpenFoam ver .2.1 x and the results are acceptable. in the second step to find out the effect of using different numbers of processors in parallel method I applied snappy hex mesh to save time for generating mesh.
In this regard,initially I run the propeller in tutorial of open foam 2.1 x . The case works on my PC but when I exported it to run in a network and run by much more nodes is going diverge although some times It approached to results for employing different processors and finer and coarser meshes.
I think there is bug when running the case as parallel.
I would like to receive your opinions in this case.
