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

The syntax in parameter files is

[ GfsVariableFunction ] { tolerance = 1e-3 ... }

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. The parameter block is optional and follows the syntax (and default settings) of GfsProjectionParams.

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