Getting values > 1e37 for equivalent plastic strain in my results. This is with higher loads. At lower loads, the values are in the right ballpark, but contour looks odd (compared to all other results). Meanwhile, all other outputs seem reasonable/correct, including the nonlinear plastic strain.
Is there something I'm doing wrong to calculate equivalent plastic strain? Or known bug?
