Hi

I'm not sure its the solver that is doing something wrong, I have problems to understand your model.

First, when you select material from the library these are given mostly as function of T (and p for gases). But if you redefine T to T2 for some physics, the library material temperature variable is NOT renamed, you must check and correct it manually, if required.

I have also problems to understand your two chcc's, over the same volume ?

But it's Friday night and I'm rather tired,

Hope it still can give you some clues
Good luck
Ivar

This problem has been solved. It was a initialization problem. With default segregated solver, when opened in v4.3, there is no more this problem...
