Point Mass Source
The Point Mass Source node models mass flow originating from an infinitely small sphere centered around a point. It is available for points in 3D geometries.
Point Mass Source
Enter a value or expression for the source strength, N0 (SI unit: kg/(s)). A positive value results in mass injection from the point into the computational domain, and a negative value means that the mass is removed from the computational domain.
Point sources located on a boundary or on an edge affect the adjacent computational domains. This has the effect, for example, that the physical strength of a point source located in a symmetry plane is twice the given strength.
