A point, line or area at which mass or energy is added to a system, either instantaneously or continuously.  2, record 3, English, - source

Record number: 3, Textual support number: 1 CONT

An incompressible fluid will possess sources or sinks of mass only at points where the divergence of its velocity vector is nonzero; a source is associated with positive divergence and a sink with negative divergence(convergence). The fluid is usually assumed to pass outward from a source or inward to a sink equally in all directions along radial lines.  3, record 3, English, - source

Conversely, a sink is a point where mass or energy is removed from the system.  3, record 3, English, - source
