Dear all,


I want to perform a QMMM simulation of a polymer molecule inside a zeolite. I want to fix all the zeolite host atoms. So the QM region of this zeolite host will be fixed as well.

Is it possible to fix one of the atoms in QM region? (others are free).

Many thanks

Best regards
Lifeng

Hi Lifeng,

Please read http://www.nwchem-sw.org/index.php/Release61:Constraints I think that explains what you need.
