Hao Guest Posts: n/a	I doing a simulation in a 2D rectangular domain. I set all the four boudaries "Wall". The volume is full of air. And I heat it up at one wall (bottom). I use "ideal gas law" here. One thing i just cannot understand: the pressure unchange. The CFD code i used is CFD-ACE. Has anyone happen to meet this kind of problem?
