zone.tetra.strain.rate
Syntax
- t := zone.tet.strain.rate(z<,ioverlay><,itetra>)
Get the zone tetra strain rate based on the current velocity field.
If ioverlay is specified (an integer from 1 to 2) then only the strain rates of the tetra of that overlay are returned. If itetra is specified as well, then only the strain rates of that specific tetra is returned.
The total number of tetra in each overlay depends on the zone type (brick, degenerate-brick, wedge, pyramid, or tetrahedron).

.Returns: t - zone tetra strain rate tensor or value
Arguments: z - zone pointer
ioverlay - optional overlay index of the tetra, from 1 to 2
