Blanking Option in CFD-VIEW for Visualizing Chimera Grids

CFD-FASTRAN uses closed surfaces, such as walls or blocked regions, to create Chimera holes (or blanked regions) in a grid. By default, the number of buffer layers is set to 1. This means that a closed surface will cut a hole in any mesh that overlaps it, and the initial "blanking" of grid cells defines the hole.
