Hi I did run init_hf_lapw and I saw no sign of errors upon running it, however, I ran it from the web interface the first time. I just restarted the calculation using bash and have confirmed the ibz and fbz files exist. The reason that I am interested in hybrid mode is that I actually have 96

Dear wien2k users, We are trying to do DFT simulation on a spinel ferrite (normal spinel) having Fe atom distributed over all the octahedral sites (16d). However, during initialization we have achieved the following error forrtl: severe (24): end-of-file during read, unit 81, file

Re: [Wien] Mo+Si, is a U needed ?

2015-03-03 Thread Peter Blaha
Mo is a 4d element and its electrons are much more delocalized than 3d. This gives then a fairly small U and a large bandwidth, so that common wisdom would be: no U (or at best a very small one). Of course, details depend also on the type of compound, i.e. Mo-NN distances, coordonation,

2015-03-03 Thread Peter Blaha
No, you cannot restrict the magnetic moment of individual atoms. You can only set the starting moments of each atom for the scf cycle and eventually the total moment of the cell. Am 04.03.2015 um 05:19 schrieb محمد ارشد فرحان: Dear Wien2k Developers and user, hi, I'm studying charge transfer

I do not understand your.machines file. It is the worst possible setting you can make: a) with a 2x2x2 k-mesh you have at most 8 k-points (or in your case 4 ??, depending on symmetry), so using more than 4 lines is absolute MEANINGLESS. b) The mpi-code has to use a different

Hi All, I am trying to run a hybrid functional calculation on a 96 atom system using PBE0. I successfully used a PBE functional using the test machines file below that is a hybrid k-point/MPI parallel job. While I posted a day ago about a failure due to missing ibz fbz files when I

I think you need to be concerned about the first error: mv: cannot stat `aCGT.vector': No such file or directory The other errors probably just follow because of it. What WIEN2k version are you using? I remember seeing almost the same sequence of errors before because of how the SCRATCH

I still don't understand why the script run_lapw does not find the ibz and fbz files. Maybe not related to this, what are you specifying for the SCRATCH directory? With hybrid functionals it is mandatory to use ./ (the directory of the calculation) for SCRATCH because of the files
