GfsSourceTension adds a surface-tension term to the momentum equations, associated with an interface defined by its volume fraction and curvature.

The syntax in parameter files is:

[ GfsSourceVelocity ] TRACER SIGMA KAPPA

with

TRACER
the name of the variable holding the volume fraction defining the interface (typically a GfsVariableTracerVOF),
SIGMA
the (constant) value of the surface tension coefficient,
KAPPA
the name of the variable holding the curvature of the interface (typically a GfsVariableCurvature).
