Seeking for sample code to modify Anisotropic Hyperelasticity (AHYPER) formula using UPF

      I am trying to modify the existing formula ( anisotropic hyperelastic formula) to have 4 summations of invariant I4 instead of the original one with 3 only.


      Is there any sample code for UPF available for the existing anisotropic hyperelastic (2 fiber)? Else is there any suggestion on how i perform this modification?


      Thanks.

      Hello,


      This does not look pre and post processing question. Can we move this to some other category from current pre and post processing category. This would give better chance of getting answer to this questions. Let me know which category and I will move it.

      The topic is related to material modeling so i previously thought its under pre-processing. Is there a section for UPF?

      Hi,


      Defining material may fall in set up. Depending on physics we have different categories. Let me know which one you want me to move this thread.

      Please refer to Anisotropic Hyperelasticity tutorials, which may be of help.

      Hi Serene,


        Please see Jim's response to your question. UPF for Anisotropic Hyperelastic material is currently not available but is expected to be a beta feature in the next release.


        So, as Jim previously mentioned, you might have to do a lot more work but it might still work with the usermat() routine. Please see this post for help on getting started.
