This shows how a high precision solver enables modeling of elasticity of a steel beam, with material parameters ranging from elastic to perfectly stiff. For this model, an iterative solver of the type typically used in game physics engines (Gauss-Seidel/SOR), does not give precision anywhere close what is required to do realistic material modeling.
Thanks to the sparsity of the system, the direct solver used here is also much faster than an iterative solver, even for a very small number of iterations.
wow very cool
