class ComputeVertexCauchyGreenEnergy : public ComputeForceClass

Compute Cauchy-Green stretching energy for a triangle Stretching energy density is calculated as.

\( E=\frac{k}{2}\frac{1}{1+\nu}\left(Tr\left(C^2\right) + \frac{\nu}{1-\nu}\left(Tr C\right)^2\right) \), where \( k \) is the elastic constant, \( \nu \) if the Poisson ratio, and \( C = \frac{1}{2}\left(FQ-I\right) \), with \( F \) being Gram matrix for strained triangle, \( Q \) being the inverse of the Gram matrix for the unstretched triangle and \( I \) is the identity matrix.
