Considering the linear elasticity and corotational approach, the code (initially starting from FastTetrahedralCorotationalForceField) should be cleaned and made coherent:
consistency of functions (involving both direct and iterative approaches)
data structure (e.g. vector of Young's modulus, if size = 1, set as constant)
