I am trying to make a very simplified model of a natural draft cooling tower. I need to create a region of porous media that is also a constant heat source, heating the air to create a natural circulation in the tower. I have found the option for creating a porous media, but I have the following problems:
Is it possible to assign the porous media to a volume from the original CAD file? Air will flow inside and outside of the cooling tower, so I need a more exact volume than a geometric entity like a cartesian box or sphere.
How does one add a heat source, either to the porous media volume or in general?
Here is my project: https://www.simscale.com/projects/swingo/half_cooling_tower_with_fill_media_1/
Thanks in advance for any help you can give me!
