I have started working on openfoam very recently, I need to simulate fluid flow of a axial in radial out pump and I'm have tremendous problems with boundary conditions..
**Especially fvsolution and MRFproperties. **
Also I have just one rotating patch around and including impeller. I'm not even sure how to use MRF properly to rotate the impeller body. When I try to simulate (delta t=1; writetime=5; total time=10)
Folder 0 & 5 have simulated values but folder 10 is completely filled of 'nan'.. It gives an error in paraview saying "Expected a number instead of a character n"..
Also is it possible that one I simulate all the 3 volume bodies separately and then somehow join them together? I could do that since original mesh is in ICEM anyway.
Please help.. I'm open to any suggestions that might be even remotely useful.
