Re: Is optimization in DLC with some frozen Cartesian coordinates possible?

Hello,

It is possible.

 
 $contrl nzvar=1 $end
 $zmat dlc=1 auto=1 $end
 $statpt  ifreez(1)=1,2,3,4,5,6 $end

will freeze atom 1 and 2 (you need to specify three Cartesian
coordinates of atom you want to freeze) Thus ifreez(1)=1,2,3,4,5,6
means freeze Atom1X, Atom1Y and Atom1Z, and the same for atom 2.

Kind regards,
Alex Granovsky
