How to setup wear analysis in optistruct.

Eddy _20769

Hello everyone. How to set up wear analysis in optistruct. I see in ver 2023 already can calculator wear in the result. but I don't see any posts or guides.
In my example, I want to set up wear analysis in hypermesh 2024 with Sovler optistruct 2024, and the case about a tube rotating through a bearing. I don't know how to set parameters like wear coefficient, hardness, and exponents.... card image...
Thanks for your opinion.

Thanks, Mr Rajashri,
I have read the blog, but it does not show the things I need. I want to know how to set up contact, material, and card images to have the wear results.

Hi Eddy,

Attached is the example file.

You can see in CONTACT the wear parameters are defined like below.

$$
CONTACT 1 0.1 1 2
+ N2S CONSLI
+ WEAR0.000001 1. 1.6243 0.5
$

This is not yet supported in hypermesh GUI, so you can edit only in .fem file as text.

Thanks
