<div dir="ltr">Dear wien2k users,<div><br></div><div>I am trying to minimize the positions of the compound YIG to get forces below 1 mRy/bohr but instead I am always getting forces around 3 mRy/bohr, and in every iteration I am getting the warning message: "LOPW-exhausted for atom 4 PASS 1 had to reduce check 0.010000", where atom 4 is the Oxygen and it is the only with free structural parameters.</div><div><br></div><div>I have searched the mailing list ([<a href="https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg13899.html">https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg13899.html</a>] and [<a href="https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg14393.html">https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg14393.html</a>]) and it seems that the problem is a low RKmax but I have done the calculations from RKmax=6 to 10 and the warning persists.</div><div><br></div><div>
<div style="font-size:small;text-decoration-style:initial;text-decoration-color:initial">Also, if I do a 1x1x1 P supercell (160 atoms) this warning disappears.</div></div><div><br></div><div>Should I increase the RKmax until I no longer get the warning or is there an alternative?</div><div><br></div><div>Best regards,</div><div>Rui Costa.</div></div>
