Hello,

I am trying to carry out a harmonic analysis from a static structural analysis with pretension on bolts. I have done it in two different ways, through a link directly in the Workbench and through the LDREAD command. However, through I get two different results.

LDREAD reads results from the results file and applies them as loads, whereas doing prestressed analysis is not the same thing.
I think you want to see the approach of doing prestresses analysis using command objects. Please see if the following link helps you where it is indicated how to do a linear perturbation:
Chapter 9: Linear Perturbation Analysis (ansys.com)

Hello Ashish
First of all, thank you for your cooment.

I read the chapter that you recommend me but I don't know how to use the linear perturbation with commands in Mechanical (workbench). Do you have any example where is used this function?

Best regards Mihai
