      Dear Users,

      I would like to simulate the wear in a hip implant during a walking cycle. I've attached the geometry in this discussion. Outer part is fixed and i

      How are you getting results when you do this manually? Does recording help to record required scripts? Please check:

      Hello Aniket,
      I can't get wear results. Only results I get are contact pressure and sliding displacement.


      Those pictures are my code and the geometry for wear. This is a ball and socket joint. No translation but every rotation is free. If there is something wrong with my code or you have any suggestions, please shoot it!
      Thanks Kayra Bolcal

      wear is direct nmisc output for contact elements, and can be output like this: contnmisc172 for wearX, contnmisc176 for WearY and contnmisc180 for wearZ as user expression in the user-defined results in mechanical post tree.
      By default these results are not stored, you need to store them by selecting yes for storing contact misc result items.

      I myself am doing a wear analysis but cannot seem to get it right. I am weak in the commands part.
