I trying to optimize my 2D material, only force is not converged. Here I shown the final result. Anyone please give me what is the parameter i have to change to make the converge the system.

BFGS: Warning - looks like this system is as converged as possible.

       Maybe your geometry convergence tolerances are too tight?
