Line Mass Source
The Line Mass Source node adds mass flow originating from a tube of infinitely small radius.
Selection
The Line Mass Source feature is available for all dimensions, but the applicable selection differs between the dimensions.
Line Mass Source
Enter a value or expression for the source strength, N0 (SI unit: kg/(m·s)). A positive value results in mass injection from the line into the computational domain, and a negative value means that the mass is removed from the computational domain.
Line sources located on a boundary affect the adjacent computational domains. This effect makes the physical strength of a line source located in a symmetry plane twice the given strength.
