I am using OpenFoam 2.2.2. I'm getting the following error when trying to solve laplacianFoam for a cylinder using a slight modification in which laplacianFoam takes a tensor as the coefficient D.

Floating point exception (core dumped)

The problem appears to be with the mesh that I am using because the same solver will run just fine for the provided flange example. The solver also works on the cylinder mesh if a scalar is used for D.

I have attached both the model files in cylinder.zip and the slightly modified solver so that it uses a tensor coefficient in laplacianFoamT.zip.

Any insight into how I can get this to work would be much appreciated.

Thanks,
Jim

It appears that the original mesh that I used with blockMesh was not suitable. I have remeshed the cylinder using snappyHexMesh and the swiftSnap tool developed for blender (it works really well!)

The revised case is attached below.
