Hello all,

I have a bit of a messy case setup in OpenFOAM so I hope you'll forgive me. My geometry is similar to a pipe with internal baffles and has 3 patches, inlet, outlet and walls. I have meshed this using snappyHexMesh. As a result I was working in a copy of the motorbike tutorial folder. After the meshing was done however, I realized that the turbulence model was not applicable to my case. As a result I changed the case folder with elements from the icoFoam cavity tutorial. However on execution, the following error is displayed.

Floating point exception

Since the error is pretty generic I dont know how to deal with it.

I'am sharing a zipped copy of my case folder as well.

Could someone help out?
