Hi all, 

I'm writing a VUMAT for a coupled temperature displacement and seem to be having some issues defining my temperature-dependent stresses. I was wondering if this might be due to an issue in the storage of the temperatures and stresses? Of course the stresses and temperatures are stored in the material points (nblock), however, I am confused as to what the material points are, since for the displacement problem, the results are computed at the integration point, and for the temperature problem, the results are computed at the nodes. Simply put, would tempNew(km) be the temperature at the same material coordinate as stressNew(km), or is km for tempNew referring to a nodal value, and stressNew(km) referring to an integration point value?
