Hello all,

I am trying to make a surface plot of the first strain invariant in my model.

In the solid mechanics module, I don't seem to have access to it. However I have seen documentation which states that the first strain invariant is a variable I can use in post processing. It is listed as a solid application mode variable, but I can't find it on the model tree anywhere.

Regards,

Eric

Hello Eric,

See the attached screenshot.

Note that the "Replace Expression" button offers a query field, which I used here to look up all preimplemented quantities whose name includes "first". It's very convenient.

Best,

Jeff
