RuntimeError: Lattice converged to a = 3.593088870450398 Angstroms and c = 7.163020192865636 Angstroms (c/a = 1.993555), which means the distance between an atom and its nearest neighbor in an adjacent layer is 4.138918189716775 Angstroms.  The model cutoff computed was 3.5999999965727416 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.
