GQCConstraints

GQCConstraints or GQCC for short is a python library, based on GQCP, that can be used to run several constrained quantum chemical calculations.

Constraint and symmetries are closely related and as such, applying different kind of constraints on quantum chemical calculations can lead to some very interesting insights.

Getting started

In order to get started you first of all need a working GQCP docker container.

First install Docker. Then pull our GQCP image to the infrastructure in question.

docker pull gqcg/gqcp

Next, on top of this installation you can install GQCConstraints.

pip install GQCConstraints

To use the code import both GQCPy and GQCConstraints.

import gqcpy
import GQCC
