The Mass Source node adds a mass source (or mass sink) Qm to the right-hand side of the continuity equation: Equation 7-18. This term accounts for mass deposit and/or mass creation in porous domains. The physics interface assumes that the mass exchange occurs at zero velocity.

Enter a value or expression for the Source term Qbr (SI unit: kg/(m3·s)). The default is 0 kg/(m3·s).
