The following feature is something that is often done in the filtration industry.
I would like the ability to define porous media by an imported volume. In the project attached you will see I have 2 volumes one for the flow domain and one for the porous medium (air filter). Currently all we can do is define a porous media by geometry primitive. This will not work for a cylindrical air filter where the flow moves radially. As shown in the picture the flow would come in from the inlet into the inner diameter of the filter. The flow would then move radially through the porous media and finally around the outside diameter of the filter to the outlet.
Here is a project example of this geometry: https://www.simscale.com/workbench?publiclink=70955638-8a78-43a6-bd91-a5cb4642aef5
I would use solid_1 as the flow domain and solid_0 as the selection for porous media instead of a geometry primitive. Note: solid_0 is overlapping solid_1.
In the end I would need to be able to also define the porous media resistance in a cylindrical coordinate system. Where I could define resistance in the radial, axial, and tangential directions. Can this be done currently? Or, would this be another feature to vote for?
