Hi Harry,

Can you share more details about the issue? As per the image attached, it looks like the curve fitting is not giving proper coefficients for the Mooney-Rivlin model. Do you have test data for a given material? Did you try other hyperelastic material models? Please check the below video on curve fitting and see if it helps.
