Okay Sir, I will do it, but following Gaussian output may, perhaps, make
clear what I want to say, this is output of Gaussian for normal termination
of every sander minimization step:
*Maximum Force 0.129720 0.000450 NO*
* RMS Force 0.019740 0.000300 NO*
* Maximum Displacement 0.095943 0.001800 NO*
* RMS Displacement 0.021493 0.001200 NO*
* Predicted change in Energy=-5.123724D-02*
and Gaussian adds this energy to sander output. So how one can believe
that it is optimizing the system when proper convergence is not achieved.
Is it Ok, and can I trust that Gaussian is doing well here?
