+||13/06/16 || MS || '''Only if [../../app/inipar#masking_method masking_method] = .T.:''' Over-determination of Neumann boundary condition of perturbation pressure in poismg_noopt.f90 if a grid point within topography adjoins to two or more 'flow' grid points. This case, Neumann boundary conditions are not correctly set for the 'flow' grid points as the perturbation pressure inside topography is an average over all the adjoining 'flow' grid points. At this point it should be noted that is '''is not''' the reason for the velocity blow-up in case of complex topography. ||

 ||09/05/16 || MS || For very complex topography, e.g. very narrow street canyons or corners that are resolved by only one or two grid points, the use of [../../app/inipar#psolver psolver] = 'multigrid_noopt' and [../../app/inipar#masking_method masking_method] = .F. can lead to a blow up of wind velocity. Please see [#remark1 remarks] below. ||
