simply resetting the coordinate will move the center of the mass of the whole |

system. To avoid this problem, a new method was used at OOPSE. Instead of |

|
resetting the coordinate, we reset the forces of z-constraint molecules as |

well as subtract the total constraint forces from the rest of the system after |

|
force calculation at each time step. |

Worthy of mention, other kinds of potential functions can also be used to |

drive the z-constraint molecule. |
