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
- 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).
