Tool which can be used to generate high quality unstructured grids for use in FVCOM. The SMS outputs must be post-processed to conform to the input format required by FVCOM, although since both SMS and FVCOM store the unstructured grid data in ASCII files, the conversion is straightforward.

SMS can also be used to interpolate scatter data (with different priorities) onto the unstructured grid to generate the requisite depth values at each grid node.
