PARAM, SMDISP
Bulk Data Entry This parameter is used to specify that small displacement formulation or large displacement formulation is used.
Parameter  Values  Description 

SMDISP  <0, 1>  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.
