Question #690803 on Yade changed: https://answers.launchpad.net/yade/+question/690803
Luc Scholtès proposed the following answer: Hi Guilherme, If you want to impose a unidimensional flow in your sample along a given direction by imposing a pressure difference, you need to set condIsPressure=1 for both in and out coordinates along this direction and to define the in and out pressures. For instance, in your case, it seems that you want to impose a pressure difference P2-P1 in the y direction so you need to set bndCondIsPressure = [0,0,1,1,0,0] bndCondValue = [0,0,P1,P2 0,0] Like this, you should be able to compute the permeability following Darcy's law (or a derivative of it) by relating the computed flux and the imposed pressure difference.
