Thank you Dr. Marks for the comments. Case.struct file is attached. 1) With a largish unit cell like this you only need 1 k-point for optimization
Noted. i will repeat calc. with 1 k-point for optimization. 2) An RKMAX of 3.5 is absurdly small. You probably misinterpreted the CIF file, which I suspect contained partial occupancies. Ok. i will repeat calculation with Rkmax=5. Please see case.struct, no partial occupancies. 3) It appears that your cell contains Hf/K/C/O. You probably should have RMTs for C and O near to 1.0, which means that you need an RKMAX of about 5 for a decent calculation. Yes. RMT for C:1.15 & O:1.04 is defined. 4) Why are you using Wien2k 16.1? Is this a legal copy? If it is legal then you should update. If you "acquired" 16.1 from somewhere then I doubt that anyone should help you. i purchased wien2k in 2016. Installed at 6 core PC, works fine. For supercell calc., installed at cluster but could not make it to run for mpi_parallelization. Lot of time has gone in debuggin. I dont want to disturb w2k_16 installation at cluster since we spent lot of time on this. But Mpi-parallelization still could not be done. thanks, A. Kumar
