Re: [Wien] Error for sphere overlapping
Dear Abo I have checked case.in0 it shows following: TOT XC_PBE (XC_LDA,XC_PBESOL,XC_WC,XC_MBJ,XC_REVTPSS)NR2V How to manage this error if there is format difference.

Re: [Wien] Error for sphere overlapping
Yes, you can try decreasing the RMT, where it is recommended to use setrmt (terminal) or set automatically RMT and continue editing (w2web) [ http://www.mail-archive.com/wien%40zeus.theochem.tuwien.ac.at/msg07996.html , http://www.wien2k.at/reg_user/faq/rmt.html ]. Or you might want to upgrade from WIEN2k 13.1 to 14.2 in order to use reduce_rmt_lapw that was released in WIEN2k 14.1. As it says on the webpage at http://www.wien2k.at/reg_user/updates/ : *reduce_rmt_lapw*: (should be called when a structure optimization stops due to overlapping spheres. It will save the current calc. as case_old_rmt_XX, reduce sphere sizes by a certain amount (3 % or -r XX) and extrapolate densities on the new radial mesh, so that afterwards you can easily continue with the minimization) However, if any of the atomic positions have moved too close to each other, decreasing the RMT might not work and the atomic positions would have to be adjusted so that the atoms do not overlap. Check the failing struct file with xcrysden and/or x nn, these programs can help you see if the atomic positions are too close. I assume the Li positions are constrained in the calculation as you mentioned before [ http://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg12403.html ]. I haven't tried constraining positions during optimization. So I don't know, but maybe constraining positions can also lead to such a problem. Also, your RMT of Li looks like it might be too small. From what I have seen in literature, the RMT of Li in LiFePO4 is around 1.97 a.u. [ J. Phys.: Condens. Matter vol. 22 p. 275501 (2010): http://dx.doi.org/10.1088/0953-8984/22/27/275501 ].

I faced with error that caused by sphere overlapping due to atomic movement. My structure is LiFePO4 and I chose Rmt as following Li-0.88 Fe-2.0 P-1.66 O-1.21 Then how can i solve this error? Can I decrease these values more?
