Figure 5. Close mesh holes. (A) z-bond assignment. Mesh from Fig. 1 before refinement. Slice numbering follows Fig. 1 F. Mesh elements are labeled. Holes and pentagons of slices 5?8 are shown. Mesh after first (B) and second iterations (C) of the hole closing procedure and z-bond updates is shown. Added beads, added z-bonds, and new distance-based z-bonds pertaining to the holes in (A) are marked. Inset of (C) is zoomed view of area in the red rectangle. z-bonds marked by X were removed after the procedure to limit z-bonds to one per bead for each neighboring slice. (D) Mesh after depressing protrusions (see Fig. 6 for further detail). Note the lack of holes. (E) Mesh after final refinement steps (smoothen BOC and equalize bond length). Note decrease in the number and size of pentagons.
