Variational integrators form a general class of structure preserving numerical algorithms for simulating dynamics. In this talk, we will present a new variational integrator, which combines techniques from spectral methods with the galerkin variational integrator framework. It will be shown that, under certain conditions, variational integrators constructed in this way inherit both the excellent convergence properties of classical spectral methods as well as structure preservation.
