user failure criteria in laminate modeler

[stressboy]

hello,

I try to impliment my own failure criteria in laminate modeler, and I encounter a few problems.
the example file found in the help guide does not work. patran return an error where it explains that I must add functions: check_mat_allow_valid, name....
I do not know how to use them.

if anybody has a tip, it would be great.

Thankx

from my experience, if PATRAN fails you, do the direct code in the NASTRAN bdf file, and modify the laminate definition accordingly.
