For structured grids ShowGrid computes the grid lines. There are different display methods: show all grid lines, show only the grid lines on the outer surface (hull), show only three sides of the hull (the user may choose among 8 options that determine which three sides are selected), show only the bounding box or show the edge lines.
For unstructured grids ShowGrid displays only one cell. The cell is selected through the parameter position.
ShowGrid is available for all COVISE versions on all supported platforms.
|options||Choice|| The display method:
|pos||Slider||This parameter (position) has an effect only for unstructured grids: it is the index of the cell to be displayed.|
In order to correctly interpret the meaning of the three_sides family of choices a remark is here in order. Any point of a structured, uniform or rectangular grid may be fancied to be characterised by three integer labels ni, nj, nk in the ranges between 0 and Isize-1, Jsize-1, Ksize-1. Corner +++ stands for the corner with (0,0,0) labels, corner ++- for the corner with (0,0,Ksize-1) , corner +-+ for the corner with (0,Jsize-1,0) , and so on.

Example 1 (Structured Grid):
Look at the map ShowGridStructured.net. Make sure to set the parameter Coord_Type for GenDat to "Half_cyl" as shown in the ControlPanel. With this parameter setting, the module GenDat generates a half cylinder as structured grid (In addition, you can change the GenDat parameters xSize, ySize, and zSize in order to modify the grid produced by GenDat.)
The following images show the results for options
Example 2 (Unstructured Grid):
In ShowGridUnstructured.net the module RWCovise reads in the unstructured grid of a channel with two inlets. The module DomainSurface computes the outer surface of the grid and the module CutGeometry cuts the upper sides so that we can look into the channel. The module ShowGrid computes the edge lines of the cell at index 200.
