In order to get away from some open boundary troubles, it may be wiser to have a larger domain for the wave model w.r.t. the hydrodynamical one. Now, is this feasible when we run the coupled version of ROMS? I.e., can SWAN and ROMS run on 2 different grids? Cheers,
Sandro

Sandro: This is a test of the trac system as well as a response to your ticket.
The current implementation of the ROMS-SWAN coupled system requires the same grid for both models. The models can be tiled differently and they each can use different number of processors, but they need to be on the same grid. Future versions of the code will allow the flexibility to have each model on its own grid. However, this will require careful consideration of how to provide the missing information for the larger grid model. For example, if SWAN is on a larger grid, what currents does it get for the part that is not resolved by ROMS? -john
