Hi

I'm modeling two rack servers in a database, first i just modeled the air circulation with two rack servers having no heat generation embedded in them, rack servers have one inlet and one outlet each , there's one inlet and two outlets in the room, so overall three inlets and four outlets. As for boundary conditions i defined "interior" for the inlets and outlets of the racks and "wall" for the other edges, it went fine and the solution converged.
Then i decided to implement heat generation in the racks , so i embedded one block inside the racks as the representation of heat generation ... now i'm wondering what boundary conditions should i define for these blocks , tried "wall" and "interior" but it didn't work, aka solution didn't converge... I'm not sure if the problem is with boundary conditions tho ... have checked everything else and i guess something's up with the blocks as before embedding them everything was okay ...
Your contribution is highly appreciated.


Here's the mesh :
