Laying out the Grid

The grid consists of vertical and horizontal grid lines forming a rectangular array of cells. To lay out the grid, select "Grid" from the "Active Data" selector. The grid may be edited on the drawing area or on the Grid Window.

• Create a uniform grid
• Use the methods below to create a non-uniform grid.
• Move the grid
• Resize the grid
• Add grid lines
• Move a grid line
• Delete grid lines
• Subdivide a grid interval

Notes:

• The grid should be sufficiently large to cover the domain.
• The numerical model VS2DH (all versions) requires a ring of inactive border cells around the active grid. These border cells are automatically added by the preprocessor and are not shown or considered in the graphical display.
• The compiled version of VS2DH 3.0 included with this program can handle approximately 35,000 cells. Users requiring more cells must recompile VS2DH 3.0 with larger array sizes.
• When working in radial coordinates, the left edge of the grid must coincide with the z axis (r = 0).
