zone.test.quality

Syntax

f = zone.test.quality(z,itype)

Get a measure of the zone quality, or how the zone shape may affect solution accuracy. itype must be either 1 or 2; any other value causes a return value of 0.0. itype = 1 indicates a test of volume over edge length. itype = 2 indicates a test of skew. Both return the minimum value obtained over all internal tetrahedrons. A return value of 1.0 indicates an equilateral tetra.

Returns:

f - a measure of the zone quality

Arguments:

z - a zone pointer

itype - 1 for a test of volume over edge length, 2 for a test of skew
