Perforated Plates in an External Analysis

Good Afternoon,


I am continuing forward with my convection studies in sheet metal enclosures. I have recently switched to external analysis based on a reccomendation from these forums. The results seem more accurate than before. But of course they are taking longer to converge.


So I wanted to replace some of my vent patterns with perforated plate conditions to reduce calc times. Now I am questioning how the results will turn out, or if perforated plate will even work for what I am doing.


I will simplify my problem to give a quick example.


I have a vented sheet metal enclosure with a heat source inside. I am currently waching air enter and exit the enclosure through the many vents. If I change the large pattern to a single plate with an eviormental pressure & perf plate condition. Will it still allow pass through? Is there any way to accomplish this? I know with fans, I was told you can just put another fan on the other side to simulate passthrough. Also not to go off on a tangent, but does anyone know for fans if you can get temperature pass through the condition? Or if you can just do velocity with an equal but opposite fan.
