If it cannot find the Fe 3p semicore states in a reasonable energy range, this means that the problem was already in the first iteration, or in fact during initialization. I'd guess your 2nd atom lost all 3d electrons in the first cycle because of wrong P states. Am 26.09.2021 um 09:47 schrieb

I'd go for a 8 core processor of the 11. generation like I9--11900K or I7-11700K which support already the faster DDR4-3200 RAM. I'd also configure 64 GB RAM and besides the SSD an additional 2TB disk (7/24 duty - i.e. made for continous use). Am 26.09.2021 um 10:12 schrieb SANDEEP ARORA: De

This comes most likely from core leakage. During init_lapw you have to reduce -ecut XXX untile the P core states do not leak out anymore. Am 25.09.2021 um 14:09 schrieb shamik chakrabarti: Dear Wien2k users,                 I was trying to simulate the optimized structure of LiFePO4. Howev
