Hello everyone, I would like to know why I am having trouble with a Mesh I've imported from ICEM using fluentMeshToFoam. It seems the mesh doesn't have problems but after running checkMesh a failed mesh check message appears. I have used OpenFOAM for about five months so I am still learning. Any advice I'd appreciate! This is the checkmesh file:

Create polyMesh for time = constant

Time = constant

Hi Jose,

I'm importing a mesh from ICEM as well using fluent3DMeshToFoam and have the same error message upon running checkMesh, I wanted to ask if you managed to solve the problem. And if so, could you give me some help as to how you did it?

Thank you for your time.

I stopped using OpenFOAM, I could not find a solution to that problem, it seems it was a problem with the mesh orientation.

Hey Jose,

That's too bad, thanks for the reply.

Can I just ask if you were using an axi-symmetric case by any chance? And what solver did you use finally if you dont mind me asking?
