local part potential

Asked by Jyh-Pin Chou on 2019-06-07

Hi all

I read the BigDFT-1.8.3 source code and get the gist of that subroutine "psitohpsi" calculate the Hamiltonian through the process

"sumrho" -> "exchange_and_correlation" -> "H_potential" -> "full_local_potential" -> eventually "LocalHamiltonianApplication".

If I understand correctly, in the end the denspot of "full_local_potential" includes exchange-correlation and Hartree potential.
Nonlocal part potential is constructed via psuedopotential projector "DFT_PSP_projectors_iter_apply".

My question is: where is the local part potential? how to separate local potential?

Sorry for my late answer which is related to the next question.

The local potential (pseudo part) is created in bigdft/src/ionicpot.f90 in the routine CreateIonicPotential.
