The criteria named Open area which account for the ratio of minimumand maximum area of the intersections of the computational domain with vertical planessouth-north and west-east directed. The wind field simulations can be seen as numericalwind tunnel runs, hence it is important to reduce the blockage effect which producesunphysical speed-up. The ideal height of the 3D model is computed automatically in order tokeep this ratio to an acceptable value close to one.The digital terrain model, marked as a box, is extracted from grid.gws.Figure 7.
