      The “TB,DP” Drucker-Prager material is for legacy elements. It has many limitations, and it is not supported by current-technology elements. Please use “TB,EDP” (Extended Drucker-Prager) material instead. When you use TB,DP, since it is not supported by the current-technology elements, that input is ignored, so the material is treated as linear elastic only. For “TB,EDP”, the input coefficients are not the same as “TB,DP”. Please see the following memo for conversion of the older Drucker-Prager material to the Extended Drucker-Prager material: http://ansys.net/collection/1096
