Optimized linear FEM for modeling deformable objects
The main contribution of our work is a technique to accelerate the real-time simulation Of deformable objects using a stable finite element method. Our purpose is to construct a preconditioner matrix for the coefficient matrix of the implicit integration scheme based on the global rotation matrix of the object. We describe some required steps to compute all optimal preconditioner in an off-line step. Our technique call be used to accelerate the element stiffness warping method and could be used to solve the system directly for objects with small deformations or for objects that appear outside of the users' interest zone.
