"WebEDFM is an effective density fluid approximation for the poroelastic model based on the full Biot–Stoll theory. The essence of the approximation is to start by setting the two relatively small frame moduli in Biot–Stoll theory to zero. Then, the effective density can be derived from the equations of motion.
