  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 ?
