<div dir="ltr"><div>Dear experts and users,</div><div><br></div><div>In addition to the above information, I want to mention that commands used in optimize.job script are "min -I -j "run_lapw -I -fc 1.0 -i 40 -p"" and "run_lapw -p -ec 0.0001". The RKmax and kmesh are set to 7.0 and 150 respectively. The energy versus volume graph (fitted to Murnaghan equation of state) looks very different from the usual. I am not getting any idea why lapw2 crashes (error in paralle lapw2 is shown in lapw2.error) for +10% of change in volume. I need your valuable suggestions to proceed with the calculation.</div><div><br></div><div> <br></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, 19 Mar 2021 at 00:39, Anupriya Nyayban <<a href="mailto:mamaniphy@gmail.com">mamaniphy@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 experts and users,</div><div><br></div><div>I was calculating the volume optimization in parallel (with 8 cores) of an orthorhombic 2*2*1 supercell having 80 atoms (in the supercell) in a HPC (Processor: dual
