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:
