Symmetry plane and errors
1 Attachment(s)
I am running a cylinder flow case with icofoam. In the tutorial, it gives a symmetry problem. But now I am running the whole geometry. I set the top and bottom boundary as symmetry plane as in the tutorial. But I got a time step continuity error.
I am a starter for Openfoam and I don't know how to set the boundary conditions in this case. could someone enlighten me on the boundary condition a little bit? |

I would appreciate your help very much! |
Hi ,
I have done this simulation. Correct your boundary conditions as follow : Code:
