Dear PWSCF users,<br>
I know this might not be the right place to ask but I just want to give a try.<br>
I use the standard uspp-736
package to generate an ultra soft peseudo potential (downloaded from
David's homepage). There is an option in the generation: "lloc"
indicates which local potential to use. However if we set "lloc = -1",
it means "simply match polynomial inside rcloc to ae potential outside"
(from the menu). What does it really mean? Is there a local potential
if we set "lloc = -1"?<br>
Thank you very much.<br>
