From my understanding, it seems that the mesh size defined in ANSYS Mechanical on the shell used to make the composite in ANSYS ACP is set as the global mesh size? I would like to better capture the stress field near the ply drop-off elements by increasing the mesh density inside the ply drop-off region and around it but doing that seems to make the ply drop-off elements extremely small since from my understanding the ply drop-off region is only represented by a single element whose mesh size is determined by the global mesh size. Thus, the element size of the ply drop-off elements arent representative of the typical length scales of ply drop-offs in manufactured composites. Is it possible to have the ply drop-off triangular region be represented as a group of elements instead of a single element to increase mesh density within that region while retaining a reasonable length scale of the total length of the ply drop-off region? I cant seem to find much documentation on advancing meshing for ANSYS ACP, currently have the 2016 ANSYS ACP user guide as reference&#8230;.
