Interface for VASP to Cc4s

This repository contains a bash script that patches the VASP source to support the Cc4s code and adds a number of additional features.

How to patch your VASP version?

Find the correct patch in this repository depending on your VASP version (e.g. ./patch/vasp.6.3.1/patch_vasp.6.3.1_cc4s.sh) Copy the patch into the ./src directory of your VASP copy. Run the patch from the ./src directory of your VASP version by typing, e.g. ./patch_vasp.6.3.1_cc4s.sh.

If everything works, you will see something like the following in your terminal

vasp.6.3.1/src$ ./patch_vasp.6.3.1_cc4s.sh
