    Hi, I have a question regarding setting up the porous media model. I am using OpenLB version 1.4.

    Section 6.3 of the documentation mentions that the permeability parameter K is calculated as K = U * A * mu * L / dP, where U is characteristic velocity, A is cross-sectional area, mu is dynamic viscosity, L is characteristic length and dP is pressure drop. I wanted to know, is cross-sectional area, pressure drop, and characteristic length supposed to be for the entire porous media domain, or for an individual cell?

    Would appreciate any clarification on this point.

    It is not for the cell!
