Porous zone definition



While setting up unit vectors for porous zones. are the vectors just the position of my radiator for example? Would it be something like below?




When setting up a 3D porous media, you have to set up 2 unit vectors. These vectors represent the principal axes of the porous media.
There’s a rule though. The second unit vector must be normal to the first one. There’s actually a third unit vector which is automatically determined by the software (third vector being normal to the first 2).
For a simple example, it would look something like this (green block = porous media):


Define Porous media by Volume Selection
