I'm using the CompressibleFlowSolver to simulate nitrogen flow in a square cavity, where there are two isothermal walls with different temperatures, and the rest of the walls are adiabatic. After looking into the manual for quite a while,  my understanding is that the wall temperature is uniquely defined by parameter "Twall", there is no straightforward way to set up a different wall temperature in the parameter file.  Has anyone run into the same issue before ?  Can you give a hint how to implement this?
