f := zone.vol(z) (3D ONLY)

Get the zone volume (in 3D) or area (in 2D)calculated using the current position of the zone’s gridpoints.

Recall that in a large-strain analysis, gridpoint positions are updated. In a small-strain analysis, gridpoint positions are not updated. This FISH intrinsic will return the zone volume (area) of an undeformed zone when used in a small-strain analysis. In small-strain, to obtain zone volume (area) that takes into account accumulated gridpoint displacements, use FISH intrinsic zone.vol.deformed.


f - the current zone volume (area)


z - a zone pointer
