Doubts Reg. Application of two or more Loads in Single Load Case

Hello,

you can refer to the first part of the following tutorial:

https://help.altair.com/hwsolvers/os/topics/solvers/os/simlab_brake_squeal_analysis_tutorial_intro_r.htm

In general you can add multiple loads with a LOADADD bulk data entry:

Thank you Solon for your response.

I will try look into the tutorial and try to establish for my problem.

Hi Solon,

Is there any possibilities in OptiStruct to apply the Displacement as a Boundary Condition to the component.

If it possible could you please share the details of it.

You can have a look at the following discussion:

Hi Solon,

I have tried to solve the simulation as per our discussions and references even though my simulation is not converging. Can you please correct my simulation procedure or specify my mistake. So, I could rectify the issue.

If Possible could you please share your mail id.

I have attached some of the image and OUT file for your reference. Kindly find the attachments.

Kindly please note that I am sovling the simaultion in Implict method.

Please take a look at this good article for Troubleshooting for OptiStruct Nonlinear Convergence Issues.

It seems that the contacts are apart at the start of the analysis causing singularity. Ensure that the contacts are initially touching, and/or add contact stabilization energy via CNTSTB bulk data entry:
