i m trying to run a flow simulation problem. The problem is stated below: I m using an aluminium body(a housing) in which there are 4 transistors giving out maximum heat. there is a heat sink mounted on the body of the housing. and above this heat sink is a fan which is cooling the heat sink. I am not able to define the boundary conditions.
You haven't actually asked any questions, and your problem statement is too vague to really help out in any meaningful way. What exactly are you having issues with?
