validation of ANSYS composite Prepost (ACP)

Hi all,

Iam presently using Ansys Composite Prepost (ACP) for composite material modelling. I looked at some tutorials and understood the procedure, but when I applied it to simple case of simply supported rectangular plate with uniform load, the results donot match the theoritical textbook results. I tried it in ANSYS Mechanical APDL, the results were exactly same with  theoritical value. Iam unable to find the mistake. Is it possible to get the validation results for ACP similar to the validation results which are available for ANSYS APDL(provided by ANSYS ).
