Section "4.5.13 Nonlocal van der Waals functionals" on page 58 in the WIEN2k 18.2 usersguide [1] has the switch "-nlvdw". Is the switch "-innlvdw" in your command below okay? [1] http://susi.theochem.tuwien.ac.at/reg_user/textbooks/usersguide.pdf On 8/17/2018 3:42 PM, Dr. K. C. Bhamu wrote:

Dear Wienk Users, I attempted to do a band structure calculation of a perovskite structure with YS-PBE0 (standard alpa parameter) with Wien2k-18.1. Up to scf and doss, I do not see any problem. But I am not getting optical properties and below is what I am getting in band.agr file: My log file

Yes, you can change it, but then you are using NOT what is called in literature optB88-vdW, but the "Bhamu-B88 functional". If you want to use what is called "optB88", you need to follow the instructions in the UG. Am 17.08.2018 um 10:04 schrieb Dr. K. C. Bhamu: aah, I got it, yes we can!!

Hii Tran, Sorry to interrupt you again, I see in UG that I need to modify case.in0 with EX_OPTB88 *EC_LDA *VX_OPTB88 *VC_LDA* I am dealing all other cases with PBE so should I change LDA to PBE or optB88_vdw is run only with LDA so that I should not change anything as in above EX/EC/VX/VC? Page

Does your structure for this SO+U case allow a shifted k-mesh [1]? If so, make sure during "x kgen" that you selected the non-shifted k-mesh as the XCrySDen website [2] says: "File-->Open WIEN2k ...-->Fermi Surface Pops-up a task window for Fermi surface creation. After several steps the

Hi, Bushra, The error message sys "No such file or directory", which could mean that tcsh is not installed. Here is my suggestion: First try, "sudo apt install tcsh" and "sudo apt install csh" and run ./siteconfig. If the same error message still shows up, then it could be because the tcsh
