I need to simulate the flow through activate carbon. I tried to create a new material using Darcy's law in wich the program requests a coefficient of permeability. By suggestions of program help I need to create a surface perpendicular to the flow, but I couldn't get it. The question is how can I get to simulate a gas crossing through that porous media. I need to create a volume of some kind? What is the process I have to follow?
