Subject: INISTATE and user material
Author: Daniel Aubram
Date: 2008-05-06 11:57:18

Dear all, Ansys manual says that an initial stress state for PLANE182 elements can be established in the first load step when issuing INISTATE command or upf subroutine USTRESS. INISTATE works fine for standard linear elastic material. However, I want to perform an analysis with a user defined material by using upf subroutine USERMAT, but now INISTATE does not put an initial stress. The stress array in USERMAT is left blank. I only changed the material characteristics input considering the user material but not the keyoption keyopt,1,10,0 (No user subroutine to provide initial stresses (default)) or anything else. Are there additional commands or options that have to be considered? I found nothing in the ANSYS manual referring to this topic. Looks like INISTATE together with TB,USER is intended to work...
