RuntimeError: Lattice converged to a = 1.8427972273568334 Angstroms and c = 4.289556260636488 Angstroms (c/a = 2.327742), which means the distance between an atom and its nearest neighbor in an adjacent layer is 2.394168004828142 Angstroms.  The model cutoff computed was 2.360506933778559 Angstroms.  Since the smallest interlayer atom distance is greater than the model_cutoff, the minimization has converged to a state where there are no longer interlayer forces, indicating the lattice is unstable.
