1. I generated the mesh in netgen and exported it to gmsh-version, Then used gmshTofoam to convert it to openFoam mesh.
2. Then i changed all the boundary conditions according to patchs in my boundary file from 'pitzDaily' tutorial folder
3. when i run simpleFoam i get the following, can anyone help with this ?

Hi, I get exactly the same error after running snappyhexmesh and then trying to run my solver (buoyantBoussineqSimpleFoam) if anyone has ideas on this I'd love to know!

I'm currently working on a 2D temperature driven flow and using a symmetry plane.

I've realised mine only crashes like this when I move the symmetry plane towards the geometry which was snapped to with snappyhexmesh. I'm not sure why it is doing this. Basically I need the symmetryplane or the edge of my domain to be closer to the geometry without it killing itself with this error...
