    composite shells

      I am using composite shells with a custom orthotropic material (with all the properties defined) on a very simple model.  When I run the model I keep getting the warning message that the material strength is not defined for failure analysis (so when I run a FOS analysis I don't get meaningful results).  I even tried running the model with the material properties found in the tutorial on composite shells - same warning message.  Any help is appreciated.
