Hello there, 

I was trying to do a nonlinear simulation with Polyurethane material with Model Mooney Rivlin. I got the S-S curve data(uniaxial, biaxial and planar raw data)  from Matereality, but no matter how I tweak the setup, the error message prompts up after I hit Run.

Does anyone know how to fix this error?  Could the material data be possibly incorrect?

Thanks.
