Hello!
I'm trying to simulate the compression of a silicon disc. I have the data for the compression of the disc and have already calibrated the possible hyperelastic material models. When I add the mullin's effect, i can get the job to complete for Ogden's n3 and n5 but for n2 and n6 the job aborts.

Does anyone know if the mullin's effect dependes on the material model chosen?

Thank you!
