Hey Foamers,

I am trying to adapt the buoyant cavity tutorial to a custom geometry:

$FOAM_TUTORIALS/heatTransfer/buoyantSimpleFoam/buoyantCavity

I created an .stl in solidworks and used gmsh to create a gambit .neu file. I then used gambitToFoam to convert the mesh into the appropriate files. When I run checkMesh everything came back okay, but when I run buoyantSimpleFoam, it fails after the first timestep.

I think it is something to do with my fvSchemes, but I am very new to OpenFoam, so could totally be wrong:

Code:
