Pressure Drop

For a 3D model of a porous medium, the pressure drop curve for a permeating Newtonian gas or liquid can be computed fully automatic. Mesh generation or adjusting boundary conditions is not necessary any more. After the dimensionless flow computation over a wide range of flow velocities has completed, the pressure drop for arbitrary Newtonian fluids can simply be determined by input of the density and the viscosity and the face velocity or the volume flow respectively mass flow and the inflow area.
