You say you will use the Ansys Cast Iron model, but that model requires inputs. What values will you use as input to that model?

I typically use a unit cube meshed with exactly one linear element to check that the material model is delivering as an output the numbers used as inputs to the material model.

The unit cube has a zero normal displacement on three adjacent sides, and a small positive or negative displacement on one other side. But I repeat myself, since I said this to you in your September 6 post where I provided a model that has a multistep analysis.
