Dear PWscf users,<br><br>I am thinking about adding a general periodic local potential to my system. I noted that for the specific sawlike potential (tefield), the total energy correction (etotefield) and the force correction (forcefield) are needed in pwscf code. I wonder how to generalize these two terms for a general local potential? Could anyone give me a clue? Thank you!<br>
