In [Bender+14], the authors formulated as
E(x) = C(x),
where E is the elastic energy and C is the constraint function. The current formulation follows this idea.
However, in the viewpoint of compliant mechanics (XPBD) [Macklin+16], we should formulate it as
E(x) = C(x)^T a^{-1} C(x),
where a is the compliant (inverse stiffness) parameter. With this, we can accurately simulate continuous material behaviors.
