How to solve global stiffness problem using FEA in Ansys?

 

 HI EVERY BODY!

 

      I'm studying about composite pressure vessel type 3 (that 's with liner inside) . I use Ansys to simulate my object, but i have a problem, i can't solve stress and strain for Solid64 (global stiffness). I don't know how can combine Matlab with Ansys to solve that problem.

 

      I hope some one have some experience in this field can help me. May be show me some simple example how to solve that problem.  

          Thanks for reading my problem.
