Hello, I have a question about hybrid functionals in Wien2k.As written in user guide, there are two possible choices for alpha parameter in LDA-Fock alpha hybrid functional, alpha=0.35 and alpha=0.5.I want to know, is it possible to select different alpha values in LDA-Fock alpha functional or

Dear Peter Blaha and Laurence Marks thank you so much for your help. (1) I structed my structure in this way: by using of lattice parameter of Ti2C layer the diameter of nanotube was be determined. C and Ti atoms were  located on their site by the polar coordinates. the atoms located on coaxial

Dear  P. Blaha and WIEN2K users I wanted to optimize volume of ti2c nanotube but i received some errors in lapw1 and lapw2. I used recommends  in mailing list for example i used different RMTs for Ti and C, or changed energy parameter of one atom or deleted those line in case.in1 or set energy
