Preparing nodes for model grid - Demonstration Case

Here we resume working through the demonstration case distributed with TRIGRID. Before beginning, copy the demonstration depth grid files dep.nod and dep.ngh to your working directory from /trigrid/demodata . It is recommended that any files produced from here on be given names beginning with with M.. or MOD.. to distinguish them from similar files produced earlier for the depth grid.

• Obtaining boundary nodes for the model grid
• Depth information needed for creation of model grid nodes
• Creation of model interior nodes - formation of clusters
• Extent of Depth and Model Grids - Need for trimming
