You have asked enough questions on this list, so you should know: a) Nobody can do more than make a wild guess without specific information from the error & output files. b) Ignoring the symmetry of Imma that Wien2k finds, and using instead P1 can be expected to lead to problems. c) Bad models

Hi, Yes, WIEN2k is ready to accept any k-grid when using smearing methods, however, you need to supply the proper weights. I do not know what symmetry your cell has, but I can see only weights of 1, 2 and 4 ? Is this correct ? It means you have only 4 symmetry operations for this cell ??

[Wien] generalized regular k-point grids

2021-10-14 Thread Pavel Ondračka
Dear Wien2k mailing list, Is Wien2k ready for a general k-point grid or is some part of the code assuming regular grid? I was reading some papers about how the generalized regular k-point grids have better efficiency over the standard Monkhorst-Pack ones... For example this paper has also an

Also, are your differences from one scf or did you converge? Often when converged the differences in meshes are much less in my experience. N.B., you can check forces at the bottom of case.scf2 to ensure that you have the appropriate symmetry. -- Professor Laurence Marks Department of Materials
