Hello dear foamers,


I'm having problem with the diffusion of temperatures for the gaseous phase in my model. I have a fixedGradient BC, attached to a wall, that should provide cooling.


In the end, my aim is to visualize the condensation.


Steam is initially at 100 degree Celsius, and there is a pool of liquid sitting in the bottom of a vertical pipe geometry.


Solver is interCondensatingEvaporatingFoam.



I thought maybe the problem could arise from the transportProperties.


Would anyone be able to help?
