Hi
I'm working a condensation simulation.
There is solid in the center of the square duct.
The solid shape is just a cube and surface's temperature 25C.
Inlet condition is velocity inlet: 1 m/s, multi-gas(Air:0.8, Water:0.2).
Outlet condition is pressure outlet: species(composite), temp.(temp. in field function).
The surfaces of the solid has Fluid film(shell) and 25c on the surface of solid.
But, The solid region is empty.
Fluid film has multicomponent-liquid: H2O(water), Psat: Antoine eq.

My problem is Temperature divergence from nearby solid.
Data logging is it: Temperature limited to minimum value xxxx times on model part "Fluid".

How to solve this problem?
