Problem with decomposing case with cyclicAMI

johny0688 · April 24, 2017, 06:34

Hello,
I tried to calculate case with translational periodic. I use cyclicAMI with translation. It works fine for serial run. But in parallel the error occurred and calculation can't be start. While mesh checking only the error for nonorthogonal in few cells but generally mesh is good. There is no error during decomposing.
I changed cyclicAMI for slipWall, now there is no problem with parallel run.
How to decompose case with cyclic BC? Is it possible in openFoam?

Hey Jan,

Were you able to fix the issue? I am facing the same problem with simpleFoam and cyclicAMI. I addded lines in decomposeParDict to preservePatches too. But doesn't seems to help.

Thanks,
Sugajen

Hello both of you,

maybe the reply is a bit late, but I was recently facing a similiar problem.

The solution described in this post worked fine for me: Running AMI case in parallel

Best wishes,
