Dear Wien2K users,<div><br></div><div>I am calculating some doped samples with VCA based on wien2K. I have the internal coordinates for the pure samples, for the doped samples, I just used the mini_lapw to obtain the coordinates with lowest energy. The lattice parameters are known from experiments, and the minimization was done in in-plane checkerboard antiferromagnetic configuration.</div>
<div><br></div><div>After minimization, there is a very strange problem, the structure file obtained can not initialize in the same checkerboard antiferromagnetic configuration. The x lstart fails with nstop error, I can't suppress the error by changing the atomic configurations in case.inst file. However, it could initialize in other magnetic configurations, like ferromagnetic configuration and in-plane stripe antiferromagnetic configuration. </div>
<div><br></div><div>This problem is a great headache for me, any suggestions?</div><div><br></div><div>Thanks!</div><div><br></div><div>Jiakui Wang</div><div><br></div><div><br></div><div><br></div>
