Hello Dear Prof. P. Blaha and WIEN2k users;<div><br></div><div><br></div><div>I want to optimize GaAs structure( E vs. V). At first I use experimental lattice constant and atomic position. I have two problem. </div><div>1. Nevertheless I change structure (by -10,-5,0,5,10), I can't find a minimum energy! And energy continuously decreases.</div>
<div>2. For some structures (AlxGa1-xAs) also I reduce RMT very much, but when I want to optimize it, It stops in LAPW1 because of overlapping spheres. I don't know why it is automatically changes RMT.</div><div><br></div>
<div>Thanks </div>
