What if the fiber has a complex shape?
Using the Rocky flexible fiber model, you are not limited to straight fibers. You can create your
own fiber shape using the custom fibers option, in which sphero-cylinder segments can be
arranged to form complex, multi-branched geometries, as shown in Figure 3.
Also, the modeled segments can have different diameters and Young's moduli. This allows you
to define a custom fiber with non-uniform flexibility.
The video below shows an example where each particle has a different combination of bending
stiffness for its branches.
