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 4-6).
(4-10)
For the Fracture Flow interface, the mass source is applicable to the right-hand side of Equation 4-33 in the Subsurface Flow Module User’s Guide or Equation 4-24 in the Porous Media Flow Module User’s Guide (where it is multiplied with the fracture thickness).
Mass Source
Enter a value or expression for the Mass source Qm (SI unit: kg/(m3·s)). The default is 0 kg/(m3·s).
