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

Get the volume (in 3D) or area (in 2D) of a zone using gridpoint positions that take into account accumulated gridpoint displacements.

This FISH intrinsic is meant to be used in a small-strain analysis when deformed zone volumes are required. This FISH intrinsic should not be used in a large-strain analysis (an incorrect volume (area) will be returned). Use the intrinsic zone.vol in large-strain mode.


f - the zone volume (area) adjusted for the current displacement field


z - a zone pointer
