Default Case can't run continuously in OpenFOAM?

Dear Foamers,

Recently I meet a tough problem on running cases. For my simulation, I use cyclic boundary conditions and I added a force term as pressure gradient in icoFoam solver. I ran my simulation with 72 processors. My problem is once I reconstruct my case and decompose it again, the simulation can't continue properly and the pressure field went wrong straight away, in particular funny values near the boundary.

Does anyone have any ideas about this problem? Why I can't continue my simulation when reconstruct and decompose it again (I tried copying my whole simulation to another place without any change and it ran continuously)? What was missing during the reconstruction and decomposition?

Thank you very much.

Best regards,
Tony

Nobody ever met similar issue before?

I simply reconstruct my case and decompose it again and the simulation can't run continuously. Anyone has suggestions about this? I really appreciate it.

Best regards,
Tony

Hi everyone,

Did anybody ever meet this problem before?

I checked the file and found that after reconstruction and decomposition again, both U and p fields under the same processor folder are different. Can anyone give me a hint on why is that? What might have been changed during the reconstruction and decomposition? Or is it related to the cyclic boundary I used?

Thanks in advance.
