Hi dear Former
I want to start simulating gas transfer in nano pore network. Knudson number is 0.1 and knudson diffusion mechanism is active. Gas is compressible and I want to solve this problem by rhocentralfoam solver.
I solved this problem maxwell slip boundary condition and without knudson diffusion. My results are fine.


My question : how I can implement knudson diffusion to my problem?

hello dear
if is it possible for you to guide me , i wonder how to use maxwell slip condition with rhocentralFoam
and if is it possible to use it with a steady solver like simplefoam
