A Solver Settings block allows configuring the solver.

The solver settings block requires setting either:
  * S: the grid cell size of the simulation
  * Res: the grid resolution (Res) of the simulation
//Note: If both resolution and cell size are set, cell size will be used and resolution will be ignored//

The solver settings block accepts the following optional inputs:
  * St: whether to use a direct solver (the default) or an iterative solver
  * B: the finite element type where 1 selects linear elements (the default) and 2 selects quadratic elements
  * SD: path to custom location to store solutions
  * N: number of threads for the solver to use
