Draping solver feedback

When you update layups or plies for draping, the Information window opens, and as necessary, displays the following warning messages:

• WARNING — Bad continuity detected for ply X. Draping results could be wrong. Check element normals, slope continuity and mesh density.In the graphics window, the regions with bad continuity between elements are highlighted. Element edges and the element normal are shown in yellow.

• WARNING — Flat Pattern of plyX tears or overlaps Y times.In the graphics window, the regions where elements tear or overlap are highlighted. Element edges are shown in red.

• WARNING — Flat Pattern of plyX might tear or overlap Y times.In the graphics window, the regions where elements might tear or overlap are highlighted. Element edges are shown in magenta.

The last two warnings are issued when the algorithm detects stretching in fibers, which could indicate that the ply cannot conform to the undevelopable faces. In practice, the ply would exhibit gapping or wrinkling on the mold.

Use one of the following remedial actions to improve the draping process:

• Use a different start point and draping direction.

• Add a splice in the ply.

• Introduce cut curves.
