shrinkwrapping?

HI

Is anyone working on implementing shrink-wrapping in ROMS so that calculations are not performed at land cells? We have a model grid that has 90,000 grid points, but only 20,000 are water. It is an estuarine environment that has some long tidal channels.

thanks
courtney

You can play games with the tiling so that full tiles are just on land and then do not compute those tiles.
Also, you can just write out the water points so that the history files are not filled with unused data (WRITE_WATER)

Easy enough to say and I know the NRL Stennis guys do it in NLOM, but we haven't ever coded it up.

This should just work but makes post-processing trickier.
