Mass Source
The Mass Source node adds a mass source Qm, which appears on the right-hand side of the Darcy’s Law equation (Equation 7-1).
(7-4)
For the — which is available for the Subsurface Flow Module and the Porous Media Flow Module — the mass source is applicable to the right-hand side of (where it is multiplied with the fracture thickness).
