Consider refining the mesh near bonded regions of the mesh, as well as near high curvature regions. This recommendation is based on the observed peak stress regions of all the layers.

By default, all layer information is written to the results file. For large meshes it would be wise to select the proper KEYOPT(8) setting to minimize storage requirements with the layered option for SOLID279 or SOLID186 elements. The downside of reducing the file size is that it will not be possible to postprocess the individual layers. You will need to decide what is appropriate for your analysis.

For complex material fibers, it is convenient to align the element coordinate system axis with the fiber direction.
