RuntimeError: Lattice converged to a = 4.993098343757971 Angstroms and c = 8.170831179078224 Angstroms (c/a = 1.636425), which means the distance between an atom and its nearest neighbor in an adjacent layer is 5.00009642200982 Angstroms.  The model cutoff computed was 5.000000004544876 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.
