ANP tetrahedra problems

      So I made multiple simulations with same settings and it was perfectly fine. Tho since last change in geometry it have problem. The material it does started to have problem with is COMP-A. Now it only works if COMP-A is meshed in cartesian method. Which leave much to be desired.

      nThanks for using Ansys Learning Forum. nCan you please give some more details? Like, was it working earlier without any issues for COMP-A material? What exactly you changed in your geometry? Did it change the definition of Body Interactions due to those geometry changes? nRegards,nSamir.nHow to access Ansys help linksnGuidelines for Posting on Ansys Learning Forumn

      see the error message, it complains about the equation of status you are using for tet elements, for ANP Tet, the valid equation of status are listed in the picture. So may either switch to another Tet Integration method from Solver controls in analysis settings, or get rid of tet elements, or change the equation of status of the material used.n
