The Mass Source node adds a mass source
Qm, which appears on the right-hand side of the Darcy’s Law equation (
Equation 4-6).
For the The Fracture Flow Interface — 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
Equation 4-20 (where it is multiplied with the fracture thickness).
Enter a value or expression for the Mass source Qm (SI unit: kg/(m
3·s)). The default is 0 kg/(m
3·s).
