RuntimeError: Lattice converged to a = 2.450440845275403 Angstroms and c = 2.096452872552166 Angstroms (c/a = 0.855541). The model cutoff computed was 2.09999999832366 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
