Dear folks,

I have the following problem using ICEM as a mesher. I am meshed up a bearing chamber with several different faces and two different bodies which are representing different volumes with different media (air, oil). The problem is this error-message coming out when trying to convert (fluentMeshToFoam XXX.msh) the net into OpenFOAM. I donīt know what to do or what is wrong - where lies the problem to solve?? This is the error-message:

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

Hi,
Try using fluent3DMeshToFoam , and the mesh must be saved/exported in the ascii mode, not binary.

Ok now converting/transferring into OF went fine..!
But here another error which came out while trying to run interFoam:

Hope anybody can make something out of this..!! Where can I solve the problem - The thing is: I donīt have an in-/outlet yet, they are meant to be additions later..
Thanks a lot in advance!
Cheers, Mike
