<div dir="ltr"><p>Dear All, <br> I want to optimize the double perovskite (A2BB'O6)
system. So i used the GGA exchange correlation function and its
optimized well and also calculate the properties. Since all we know that
GGA generally underestimate the band gap value for semiconductor so i
used Mbj exchange correlation to run the scf file again under the same
standard parameter such as RKmax=7, Lmax=10, E parameter=0.3 and follow
the above process gives below<br> init_mbj_lapw<br> run_lapw -i 1 -NI<br> save_l<span class="gmail-text_exposed_show">apw pbe<br> edit the file case.inm<br> run_lapw -i 100</span></p><div class="gmail-text_exposed_show"><p> after running few iteration its gives the QTL-B error </p><p> if some one have answer of this question please let me know..</p><p> Thank you all</p></div><br clear="all"><br>-- <br><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr">Thanks & Regards<div>Rajneesh Chaurasiya</div><div>Research Scholar<br></div><div>IIT Jodhpur, India<br></div><div>Mob.
