Problem with cyclic bc when run on parallel

Tek · January 18, 2010, 01:06

Hi everyone!
I'm a novice with openfoam.I try to run two channelFoam case (one for mesh constructed from block mesh,other for mesh converted from fluentMeshtoFoam) with cyclic BC.When i run parallel with the first one with many kind of decomposePar there is no problem.But it happen when i run parallel with the second one.It print to the screen " create Mesh for time = 0" and stop ,i wait for long time but nothing happen.
I hope somebody whose experience with this problem can help me.
Thanks to reading and sorry about my English.

everyhelp is appriciate!!

Hi Tek,

I've just started to run the channelFoam, and run parallel, it seems OK, even though I have cycle BC in the domain, so maybe it's due to the conversion from Fluent to OpenFoam.

Perhaps, some boundary type has changed? you may check it,

Good luck~
