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:

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

Hey MickeyMike,

At the moment I have no solution for your problem. I have a similar one. But maybe we can exchange some hints in future.

Have you read the description to 'fluentMeshtoFoam'? As I understand it, its not possible to convert meshes with multiple fluid areas and solid regions.

Cheer up!

Hey there,

thanks for your quick reply. Hm, I didnīt get to read that.. so where did you find this information about fluentMeshToFoam ? Thanks for your hint!
Cheers, Mike

HI Mikey,

Try: fluent3DMeshtoFoam! I guess thats the solution to your problem. For me fluent3DMeshtoFoam works fine. But I get the same error as you using fluentMeshtoFoam.

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!
