Dear Xzoom1,
Here you are a complete tutorial of how to use composite laminate elements with FEMAP & NX Nastran:

http://www.iberisa.com/soporte/femap/composites/nafems_benchmark_composite_test_r0031_3.htm

This is a NAFEMS benchmark (see

http://www.nafems.org)

posed to be followed for every FE code to assess accurate results. Any prestigious FE code must demostrate that the obtained results are accurate, and NAFEMS benchmarks are golabally accepted to be THE reference.

Best regards,
Blas.
