meaning of sinks?
 

A beginner question: what does it mean the term of 'SINK'? Any example to show it? Thanks.

Sink means that energy or momemtum or mass will be extracted from the simulation domain at an prescribed point of plane or volume.

Simply a negative source. I think at least one of the standard examples applies a volumetric heat source (a sink would be negative and remove heat instead of add it).

It is like a drain point for the removal of a variable.
