GfsVariable

From Gerris

A GfsVariable models a spatially variable but constant in time scalar quantity.

Note that since the GfsVariable is defined on the same adaptive grid as everything else, its computed value may evolve during the simulation as a result of refinement and coarsening steps.

The syntax in parameter files is:

GfsVariable NAME

where NAME is the name of a unique identifier. Multiple definitions of variables with the same name will be silently ignored.
