The finite element method (FEM) is used to model mechanical deformation, but simulating microstructure evolution is challenging because of the changes to the embedded surface mesh representing the grain boundaries. Furthermore, some existing formulations cannot be used for predictive simulations because they do not allow for anisotropic grain boundary properties, have unphysical anisotropy from the underlying numerical model, or allow only a restricted set of topological events that bias the grain boundary network evolution. Recent progress will be reported in developing a FEM simulation that (1) uses a volumetric mesh to eventually allow the inclusion of arbitrary material physics, (2) significantly expands the set of topological events to allow for general grain boundary network dynamics, and (3) proposes an energy dissipation criterion to identify the physically most plausible of these events. The performance of three proposed equations of motion will be evaluated and compared to analytical results.
