How to use user defined material model?

    • Aya.hassan

      Hello all,
      I want to use the modified Mooney Rivlin hyperelastic material model, but it is not embedded in ANSYS 17. How can I build the user defined file ? Does this model added to the newer version of ANSYS software?

      I also found an option  to create specific material model in the Engineering material module ( look at the following picture) , How to use it to create the modified Mooney Rivlin model ?
