What is the application/use case of cyclic load?Is this for analysis or Optimization?

Are you looking for periodic boundary condition for truncated model using OptiStruct?

As per my understanding please refer attached files for the Analysis related to cyclic load.

Hi Rahul,

Thanks for sharing. Let you if there any clarifications.

Hi Rahul,

The following file showing error while giving run.

Analyse_Fatigue_Sinus_v4.fem

This is the new feature in OptiStruct 2017.2.2...Please make sure to use the same version for run.

I am using the version 2017.2 for Preprocessing and Solving. Is it required to update the solver to give run?

As said it is supported from OptiStruct 2017.2.2 and above version.Latest version is OptiStruct 2018 and latest patch is 2018.0.1

Cyclic load for analysis only available in OptiStruct 2017.2.2 and above version ??

Shared fem file is for Sine sweep Fatigue analysis.
