        <div>                        With alpha=0.05 we are getting

              Subject: [Wien] Converging full hybrid calculation<br>
              <br>
              Dear All,<br>
                         For converging full hybrid calculation I have
              done the following;<br>
              <br>
              (1) Initially the simulation was running with alpha=0.25.
              As this parameter is not leading to the convergence, I
              have stopped it.<br>
              (2) I have executed clean_lapw to remove case.vectorhf
              from earlier calculation<br>
              (3) Set alpha=0.05 & started the simulation<br>
              <br>
              Although I have reached the energy convergence criteria
              0.0001, the charge convergence is oscillating around 0.01.
              Should I decrease alpha, even more, to get the charge
              convergence & eventually get back to alpha=0.25 at the
              end after getting the required convergence?<br>
              <br>
              with regards,<br>
