wear simulation tutorial - help needed

[Ravi]

Hello all

i am looking for a tutorial on setting up a wear simulation in LSdyna

CAn any one help in providing this or resource please 

This will help for curriculum project

Thanks in advance

Regards

A comment from a user asking related questions:

 

Hi James, we actually figured out what happened.   The issue was with soft = 2 in the contact card.  If we

do soft = 1 or remove the optional card A and B, the dynain file is written out with initial_contact_wear. 

 

I checked with Ansys and they said it was a bug with R15 solver...  it's apparently fixed in R16.

HI Ravi, I was actually the person who asked that question below and I made a 2 part video on how to do wear simulation in ls-dyna.   see below

I hope this helps, I am kinda promoting my channel a little haha www.youtube.com/@DCFEA
