GfsBoxes are the square or cubes (in two or three dimensions, respectively) of which the domain (for a GfsSimulation, etc) is built. They are also the basic element of domain decomposition for running Gerris in parallel.
The syntax in parameter input files is:
GfsBox {
pid = 0
left = [ GfsBoundary ]
right = [ GfsBoundary ]
top = [ GfsBoundary ]
bottom = [ GfsBoundary ]
}
The pid is the unsigned integer (starting from zero) that identifies the processor to which the box is assigned in a parallel run (the rank in MPI terms).
In parameter files produced by GfsOutputSimulation, it may also contain:
id- an unsigned integer identifier
size- number of cells
x,y,z- the Cartesian coordinates of the centre
