Darcy's law is valid for only

Darcy's law is an equation that describes the flow of a fluid through a porous medium. The law was formulated by Henry Darcy based on results of experiments on the flow of water through beds of sand, forming the basis of hydrogeology, a branch of earth sciences. It is analogous to Ohm's law in electrostatics, linearly relating the volume flow rate of the fluid to the hydraulic head difference (which is often just proportional to the pressure difference) via the hydraulic conductivity. Web2.2 Special treatment in OpenFOAM. If we specify a negative number to a direction of the Darcy and/or Forchheimer coefficient in the fvOptions file, this value gets multiplied by the largest value of the tensor and -1. Hence, the negative number gets a large positive one. Hence, it is easier to distinguish if a direction is valid or not and we ...
