My question is regarding user-defined failure criteria in Ansys. To test this feature, I modified the file "userfc.F" to the maximum stress criteria. I then linked this subroutine with ANSYS and created a custom ANSYS.exe file. Now when I run this custom .exe from the APDL launcher, how do I call this user subroutine? For instance, if I were to call the maximum stress criteria directly, I would use:<\/p>\n

TB,DMGI,mat#,,4,FCRT<\/p>\n

TBDATA,1,2,2,2,2<\/p>\n

where, 2 is the maximum stress criteria, and this works well. According to Ansys APDL Material reference, 11-19 are user-defined criteria #1 to user defined criteria #9, but it does not work when I use 11 instead of 2 (see command below):<\/p>\n

TBDATA,1,11,11,11,11<\/p>\n

What am I missing?<\/p>\n","protected":false},"template":"","class_list":["post-159790","topic","type-topic","status-closed","hentry","topic-tag-failure-criteria","topic-tag-macros","topic-tag-mechanical-apdl","topic-tag-upf","topic-tag-user-defined-1"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
