RuntimeError: Lattice converged to a = 1.5675321705355132 Angstroms and c = 4.332235272323724 Angstroms (c/a = 2.763730), which means the distance between an atom and its nearest neighbor in an adjacent layer is 2.347577045007479 Angstroms.  The model cutoff computed was 2.114500161670188 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.
