 Switch for topography boundary conditions in multigrid solver.\\\\
-By default, Neumann boundary conditions for perturbation pressure are used in the multigrid solver at all wall boundaries. In case of '''masking_method''' = ''.TRUE.'', the masking method is used instead (i.e. the solver runs through the topography).
+By default, Neumann boundary conditions for perturbation pressure are used in the multigrid solver at all wall boundaries. In case of '''masking_method''' = ''.TRUE.'', the masking method is used instead (i.e. the solver runs through the topography). \\\\
+'''Note: ''' If [#psolver psolver] = 'multigrid_fast', masking is always used, so that setting '''masking_method''' has no effect on the simulation at all.\\ \\
+'''Warning: ''' In case of complex topography and '''masking_method''' = ''.FALSE.'', the wind velocity may possibly blow up at certain grid points. Hence, so far it is recommended to use '''masking_method''' = ''.TRUE.''.
