f := zone.area(z) (2D ONLY)

Get the zone area 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 area of an undeformed zone when used in a small-strain analysis. In small-strain, to obtain zone area that takes into account accumulated gridpoint displacements, use FISH intrinsic zone.area.deformed.


f - the current zone area


z - a zone pointer
