PARAM, EXPISOP

Bulk Data Entry This parameter controls the element integration scheme for Nonlinear Explicit Analysis.

Parameter Values Description
EXPISOP <URI, AURI, SRI>

Default = AURI for eight-noded CHEXA elements in explicit analysis.
URI
Uniform reduced integration for eight-noded CHEXA elements in explicit analysis. One-point integration is used.
AURI
Average uniform reduced integration for eight-noded CHEXA elements in explicit analysis. B matrix is a volume average over the element.
SRI
Selective reduced integration for eight-noded CHEXA and six-noded CPENTA elements in explicit analysis. Full integration for deviatoric term and one-point integration for bulk term.

Comments

  1. ISOPE on PSLID, PLSOLID will overwrite any values defined by PARAM,EXPISOP.
  2. PARAM,EXPISOP is not applicable to Shell elements.
