Hi all,

First, flow must be developed. Then, energy eq. is activated. I could not still see convergently behaviour of continuity. I could not find out what the problem is.

Mesh metric and case setup have been checked.

If using SIMPLE pressure velocity coupling try with coupled pseudo transient. It may work.

I have already used ''Coupled'' in pressure velocity coupling. Well I have clicked ''pseudo transient'' in addition.

What does it do ''pseudo transient''?
