Dear Wien2k users,<br><br> I want to do volume optimization for Fe and Ni. I have taken spin polarization for both the cases and started volume optimization with changing volume by -5%, -3%, 0%, 3% and 5% (with respect expt. volume). After calculation of scf for -5% structure when it started scf for -3% structure it shows error in the first cycle as "error in LAPW0" and would not run further. This happen for both the cases. Now when I removed spin polarization and calculates volume optimization without taking into account this spin polarization it was able to calculate the scf for all the structures. But only with spin polarization it was showing error for the 2nd structure. Any help in this regard will be appreciated. Thanks in advance.<br>
