As it does so, the fiber goes through the polyhedron, creasting particle overlap (fig 2), instead of the polyhedron pushing the fiber away or the fiber getting folded into the open spaces. How would you suggest avoiding this issue? The simulation log suggests &#8220;increasing the polyhedron&#8217;s Young&#8217;s Modulus&#8221;, which hasn&#8217;t worked. I also tried lowering the simulation time-step which didn&#8217;t resolve the issue.
