Simulating microstructure evolution requires an understanding of the validity of various dynamical schemes. We show how underdamped and overdamped equations can be obtained for ferroelastic transitions and, in particular, demonstrate that the widely used time dependent Ginzburg-Landau (TDGL) equations correspond to an appropriate limit of the dynamics.
