Hi,


Have you tried contacting Altair's Tech Support or posting on a solver related forum?

yes, I tried contacting Altair's Tech support but didn't get any positive response yet.

Hi abchougule,


First, what are you trying to model by setting an adiabatic condition at a fluid solid interface? If the solid is included in your model wouldn't CHT be appropriate?


If you truly want an adiabatic condition on the fluid boundary you can either model only the fluid or you can set the solid medium to none.

THANKS.
It's true that CHT is appropriate in the mention condition. But for the case on which I am working on, I need the solids( to be included in the analysis) to behave as an insulator to heat transfer.

If you need to include the geometry but model it as a perfect insulator then is there additional geometry outside the wall? If so, it might be best to model the solid as a void and put the adiabatic condition on the fluid boundary.


If you need to model the solid with material for other reasons you could split the nodes at the interface of the fluid and solid. You might also think about using thermal shells to model insulation.
