libvdwxc

Van der Waals density functional (DFT) library

libvdwxc is a library of density functionals, which can be linked by density functional theory (DFT) codes, to enable the calculation of exchange and correlation energies for van der Waals density functionals (vdW-DF). libvdwxc evaluates correlation energy and potential using a convolution in Fourier space using the method by Roman-Perez and Soler.
