Hello everyone,
I would like to ask for an advice in solving a frequency response problem on a preloaded structure.
I create two load cases in a single job.
The first load case selects nonlinear Quasi-Static (NLSTAT)
the second load case selects freq.resp(direct) ,for substate(preload) ,select the first loadstep.
set PARAM,LGDISP,1
Unfortunately,the solver gives an error:
*** ERROR # 4754 ***
STATSUB(PRELOAD) of subcase 2 points to a nonlinear subcase with large displacement, which is not supported.
Best regards,
young
