Hello,

I need to determine the temperature of the gas entering a the rotor blades of a TMP. I know the temperature distribution at the steel walls of the pump port from a prior transfer simulation. Afterwards I did a molecular flow simulation (also 3D) using nearly the same geometry with the wall temperature computed before. I know that COMSOL uses the angular coefficient method and therefore information on gas properties are only available at boundaries. But is it possible to interpolate the temperature somehow, as a gas particle has (approximately) the temperature of the surface hit last. I know this can be done for the number density (with the number density reconstruction)...

Thanks a lot
Laura
