Nested Grids
From WikiROMS
Jump to navigationJump to search
<wikitex> ROMS has a nested design structure for the temporal coupling between a hierarchy of parent and child grids. All the state model variables are dynamically allocated and passed as arguments to the computational routines via Fortran-90 dereferenced pointer structures. All private arrays are automatic; their size is determined when the procedure is entered. This code structure facilitates computations over nested grids of different topologies. There are three types of nesting capabilities in ROMS:
- Refinement Grids which provide increased resolution (3:1 or 5:1) in a specific region,
- Mosaics Grids which connect several grids along their edges, and
- Composite Grids which allow overlap regions of aligned and non-aligned grids.
