Hi, I asked this as a reply but have not had any responses, I am at work on this so need to know. I created a simple surface to learn how to model parts as composites. In the shell definition property manager, the composites option is not there. It gives either thick or thin options, then a drop down shows offset, but no composites option to define ply directions etc. I have 2014 premium x64 edition, and I am not trying this in the lite version of sim. This is a static study, has worked well for other studies but I have never been able to model as composite with plies.
