<html><body>Dear Wien2k mailing list,<br><br>what is the needed procedure to run optic after hybrid calculation?<br>I've tried:<br>x lapw2 -hf -fermi <br>x optic -hf<br>after "run_lapw -hf -p" succesfully finished (calculated :GAP value is looking good, when compared to plain PBE), however the dielectric function does not shift to higher energies (in comparison to the PBE run).<br><br>Best regards<br>Pavel Ondračka<br></body></html>
