area_completer.tcl

This example shows how to use area_completer gridding rule. This rule allows you to apply completer rule in some area. This example shows how to modify resulting surface behaviour in the central (blue) area. The completer gridding rule was modified: anisotropy with angle 30 degrees and factor 3 was added inside area.

Here is the image of the resulting surface
