Re: [swanmodel-users] boundary condition on fine grid

[Sander H. <san...@bm...>]

Naser,

SWAN has no "knowledge" about grid04. You just request grid03 to output data on a certain frame (which happens to be the boundary for grid04). The only landmask that is considered is the mask in grid03. When this is problematic, you'll have to change the mask in grid03 and set the depth to some artificial level.

dear swan users;
i perform simulation coupling ww3-swan:
grid01:08km
grid02:03km
grid03:1km
grid04:300m

grid2 is the intermediate grid: pass bcs for the grid03,but when grid03 pass bcs for grid04 there is nodata on the boundary for grid04:
swan considered as land node and no wave data is offered from the nested SWAN.

why swan considered these points on the boundary of grid04 like land?

can anyone help me?

thanks for all
nasser kessali
