Reply To: Natural convection in square cavity : trouble with the discretization
Dear Mutelle,
sorry for the late response.
I looked into the implementation of the case and it seems that that example uses a deprecated way of assigning material numbers. I would refer to the laminar/cavity2d example regarding this issue. We will work on updating the deprecated case in the next release.
If you need more specific assist, please let us know.
Best wishes,
Shota Ito
