Preloading using nonlinear results for frequency response
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

Preloading with Large Displacement Nonlinear Analysis is supported from HyperWorks Solvers 2017.2.2 and above version.PFA deck and refer release notes from online help.
Thank you for your answer，it is working when i use HyperWorks Solver is 2017.3.
