Most analysis codes which generate results for laminated composite materials define the layer results as the stacking sequence number with respect to the element orientation system. If there are ply drop-offs or elements are reversed, the stacking sequence number bears no direct relationship to the physical plies.

To overcome this problem, two results sorting procedures are supported. If the analysis model has been generated using laminate modeler, the results can be sorted quite simply using data stored in the Layup file. Otherwise, results can be sorted on the basis of underlying material IDs, if the ID is only used once on every element over a selected area.
