   - `bend` [Pa]: bending stiffness.
   - `flat` [bool]: if true, the stress-equilibrium configuration is that of a straight cable; if false or unspecified, it is the configuration defined in the XML.
   - `vmax` [N/m^2]: If greater than zero, the cable is colored using mechanical stresses; the value represent the maximum stress in the color scale.

-### Shell
-
-Implemented in [shell.cc](shell.cc).
-
-The shell plugin discretizes an inextensible 2D continuum. It is intended to simulate the bending of plates where the stretching is negligible compared to other deformation modes.
-
-Parameters:
-
-   - `young` [Pa]: Young's modulus.
-   - `poisson` [Pa]: Poisson's ratio; if 0, then the material only opposed shear deformations; if near 0.5, then the material is nearly incompressible (rubber-like).
-   - `thickness` [m]: shell thickness, used to scale the bending stiffness.
