RuntimeError: Lattice converged to a = 3.537729249677139 Angstroms and c = 2.8831630214002626 Angstroms (c/a = 0.814976). The model cutoff computed was 2.50000000420961 Angstroms.  Since a > model_cutoff, the minimization has converged to a state where there are no longer intralayer forces, indicating the lattice is unstable.
Command exited with non-zero status 1
