Contacts parameters

Ali_22494

The assembly I am working on contains two objects with contacts. One of the parameters that I am interested in is frictional energy dissipation, like in abaqus. I was wondering if there would be an equivalent output response in Optistruct.

 

Thanks.

Hello Ali,

Please see the attached picture.

Also feel free to check this link.

In SimLab this option is not integrated. If you are interested in this, you will have to manually enter it in the text data of SimLab. See the picture below.

I hope this helps,

Hi Ioannis,

Thank you so much for your reply. Yes, it seems that is the one that I am looking for.

Do you have a tutorial on how to implement this in Optistruct that you can share with me?

Thanks.

Hello Ali,

Allow me to point you towards the direction.

First of all NLENRG is for the bulk data section. This means:

Right click on the solution name > Text Data > Bulk Data.

Follow the links below to find the instruction for creating such texts.

This is to classify where goes what:

This is to understand how to write bulk data:

I hope this helps.
