Hello, 

I have now managed to open the links, however I couldn't find an answer to what I was trying to find out from the documentation. In ansys if I define a mooney-rivlin hyperelastic material (per the equation below) with a d=0, this would be the result of the materal being incompresisble.

However in the mooney rivlin 2 parameter equation this would result in a calculation where 1 is divided by 0, which gives an undefined value. So my question is, what is ansys using inplace of the "undefined" value in this scenario?Â
