<div dir="ltr"><div>Dear Wien2k users,</div><div><br></div><div> I have seen the previous mailing list, in which I have encountered the same error & overcome the same problem by increasing the number of k points. In this case also I have increased the k points from 2 to 8 & the simulation is running now till without error. However, only one structure is completed in volume optimization & I have to wait to see whether there are no errors in subsequent structural optimization. <br></div><div>Prof. Peter Blaha also commented that we may use TEMP with 0.002 instead of TETRA. However, my query is if we do change that, I think, we should need to run structural optimization from scratch, is it so?</div><div><br></div><div>with regards,<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, 21 May 2024 at 19:05, shamik chakrabarti <<a href="mailto:shamik15041981@gmail.com">shamik15041981@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Dear Wien2k users,</div><div><br></div><div> I have started a simulation on metal doped LiMO2.
