Hi Foamers,

I'm trying to simulate bubbles within a pipe with OF 2.0.1 compiled from sources with ThirdParty on Ubuntu 10.04 64 bits, and a Fluent mesh imported through the fluentMeshToFoam utility.

interDyMFoam seems to run fine on damBreakWithObstacle tutorial case.

Although interFoam runs fine on my case, I get a seg fault running with interDyMFoam and the following output. It looks like there is a problem during the mesh refinement process but I wouldn't be able to tell why.

Has anybody experienced similar issues ?
Any help would be much appreciated !

Thanks in advance

Michael
