The docstring should be updated, it sort of implies that deformation_gradient is only the initial tensor but actually it needs to be fed the updated one at each timestep. Add a docstring/doctest example showing a simple 10 step loop and feeding the returned deformation gradient from Mineral.update_orientations back into the next call. This is basically the "most public" part of the API so it's good to get this right.
