PRIMER 22.1

Properties: Computing Cut-Section Properties

PRIMER is able to derive section properties (Area, 2nd moments of area, plastic moduli and section capacity) from the elements cut by the plane. Properties:

Are derived from 3D (solid and thick shell), 2D (thin shell) and 1D (beam) elements only. All other types cut by the plane are ignored.
Are calculated only from what is currently visible, so blanking and entity switches may be used to limit what is used in the calculation
Use the local XY plane of the cut-section as their frame of reference.

An example of a cut through a dummy positioned on a seat is shown below
