Not sure what others think. But it is a duct. And I was sometimes annoyed constructing these cooling inlet and outlet surfaces. The box for the porous media would have to be flush with the duct though. Maybe a frame should be mandated.

2, Would the internal flows increase computing power requirement/increase drastically the time required to do the analysis?
It should only affect runtimes slightly. I could perform a small benchmark the next days.

Thickness should be mandated. Area as well with limits for width and height, similar to like it is now. So almost what we have but with a thickness.

The box itself should not be a problem. It has to be flush / sealed with the internal walls. Or maybe actually not: If people have gaps which deteriorate the flow it would be their own fault. And I wonder what you clean up. I liked my special surfaces slightly intersecting the geometry to help out the mesher. In the end you guys then told me that was not good.

I was not aware of that. He will have to answer that.
