MIKE 21 BW - Two or more Generation Lines; Grid Spacing

Reference Manual
130 MIKE 21 BW - © DHI
NOTE: The wave direction should always be related to the general (or global)
x-axis of your model bathymetry and not the internal generation line itself.
Two or more generation lines
Figure 5.18 shows how to join internal generation lines in a corner.
Grid spacing
You must also specify the grid spacing in the x- and y-directions correspond-
ing to the bathymetry used for the Boussinesq wave simulation.
