Structured and Variational Integrators Recent developments in integration algorithms have shown that preservation of the structure of the problem often leads to superior performance. These structures are often geometric, such as the structure of a variational principle or problem symmetry. Recent algorithms that are based on a discretization of Hamilton's principle for the governing Lagrangian function for the mechanics of the problem is one method that has been developed for both conservative and dissipative problems. In the context of the mRSED program, this is especially important for the dynamics of elastic structures, including the possibility of collisions. These approaches go hand in hand with the goals of an improved infrastructure for problems of design, multiresolution simulation and model reduction.
