MPAS_GRID_DISPLAY
Display MPAS Grids


MPAS_GRID_DISPLAY, MATLAB programs which read information from an MPAS Grid file, stored in NETCDF format, and display the main (mainly hexagonal) mesh or the dual triangulation.

Usage:

grid_cells ( filename )
where displays a plot of the polygonal faces of the primal mesh;

triangulation_faces ( filename )
where displays a plot of the triangular faces of the dual mesh;
