Description

SMDISP

< 0, 1 >

Default = 0

This parameter is used to specify that small displacement formulation or large displacement formulation is used. It affects Geometric Nonlinear Implicit Static Analysis (ANALYSIS = NLGEOM) and Geometric Nonlinear Implicit Dynamic Analysis (ANALYSIS = IMPDYN).

When large displacement effects are negligible, “PARAM, SMDISP, 1” could be used to improve the convergence and performance.

If 0, use large displacement formulation.

If 1, use small displacement formulation.
