Thank you, .

I am modeling polyurethane foam. I got the uniaxial compression data from a lab test I have done. I did curve fitting outside Ansys because the Ogden-foam model doesn't have curve fitting for some reason, and I got these constants.
I have also defined the foam density, shouldn't that be enough? If I put Young's modulus (linear elasticity) the hyperelastic model will be turned off of course. I don't know why the model is not working like other ones (Mooney-Rivlin, Neo-Hooken, Yeoh .....).
