Initial stress_OptiStruct_2018

Hello experts,

I am hypermesh_optistruct user.

i have heard about a new feature in OptiStruct 2018 named 'initial stress'.

i have looked at some papers from Altair but all the information is about BULK-DATA in OptiStruct.

There is nothing about 'how to assign initial stress in HyperMesh interfaces'
Can somebody help me?

Appreciate any help.
Thank you verymuch!

Hi.

Thank for your answer,

I already found the example file but it seem very difficult for my case.

The case i want to perform is make a nonlinear-quasi-static analysis on OptiStruct with the initial stress from HyperForm result.

Do you have any suggestion or tutorial for my problem?
