GfsVariablePoisson defines a new variable which is the solution of a Poisson equation.

The syntax in parameter files is

[ GfsVariableFunction ]

The variable is the solution of the Poisson equation:

2v = f

where v is the name of the variable and f is the GfsFunction given as argument.

By default the Poisson equation is solved at every timestep. This can be tuned using the parameters of the parent GfsEvent.
