Hyperelastic Constants

Hello, Im extremely new to hyperelastic modeling and I need a simplified(do this and this will happen) answer please. I am working with something made of rubber in abaqus CAE. I am running my simulation and it cant converge on an answer at 80% of step time. I am using a mooney-rivlin hyperelastic model and I need to modify the constants (C10, C01, D1) but I dont actually know what those values are. I am trying to make my model more resistant to change. What constants do I need to change to make that happen and how proportional is the change? Thanks in advance!

I dont quite understand your question, but I recommendation is to set C01=0 and try again...
