文档介绍：: .
s For Case Control, insert the static load set selection (LOAD)
and the nonlinear static analysis parameter selection
(NLPARM).
s For Bulk Data, insert the relevant nonlinear static analysis
parameter (NLPARM).
s Prepare the model for a geometric linear static analysis (turn
off large displacements).
x PARAM, LGDISP, -1
s Generate an input file and submit it to the
solver for a nonlinear static analysis.
s Review the results.
