I've just found that I can do

foamToVTK -faceSet nonOrthoFaces

and these non-orthogonal faces correspond to places where U diverges. I have some sharp corners in the geometry, for which I...

OK, so I've implemented BC with fixed temperature, and there are still problems:

I am using mesh created in gmsh, then during the conversion step (gmshToFoam) I get a warning:

--> FOAM Warning...

Concerning the time - this I know, just the time-step seems to me to be relevant. I'll give a try to fixed temperature BC's. If I know the temperature profile along the z-axis in the cryostat, how...

I am not, and I am aware of that. Some of the energy is accumulated in the kinetics, also the integral heat flux is dependant on the real area of the surfaces, computed form the mesh. As I do not...
