I am running a simulation to predict the heat flux on the floor.

At first, I tried with the automatic meshing with a level of 6 but this takes time. Then later on, I switch on the manual meshing and it gives me the number of cells in X, Y, and Z. This will take less time.I have run both cases. The results are nearly similar.

However, I am not sure about the manual meshing becuase there is curvature refinement, refing cell, narrow cells. I don't know if I need to tune these.

Please could you clarify this and how do I know that the manual meshing is working fine and I am in the right direction.

Regards
