PARAM, LGDISP

Bulk Data Entry Activates Large Displacement Nonlinear Analysis.

Parameter Values Description
LGDISP <0, -1, 1>
0 or -1 (Default)
Large displacement nonlinear analysis is deactivated (Small Displacement Nonlinear Analysis is the default for static analysis, while LGDISP=1 is currently mandatory for nonlinear transient analysis). The corresponding nonlinear solution parameters can be specified in the NLPARM and NLADAPT Bulk Data Entries.
1
Large displacement nonlinear analysis is activated. The corresponding nonlinear solution parameters can be specified in the NLPARM and NLADAPT Bulk Data Entries.
