v5,v5c,v5x are at z=0.5. v5 (1st number) is the total potential, v5c is the Coulomb and v5x is the exchange. (For a good calculation v5x should be small, it will never be zero.) Whether one should use v5 or v5c is something I have debated with myself. I suspect that there are enough

Dear Prof. Gavin Abo Thank you very much. Yes it worked and I could finish one scf calculation with spin polarization. I have one more question. I know that, WF= VZERO -FERMI. Since I have given the vacuum along z-direction I believe I need z-component of Vzero . I found the values below from

Dear Prof Gavin Abo Thank you for your valuable instruction and for your time. I couldn't get this corrected yet. I am giving all the steps I followed  and the recieved error below. I am doing the calculation in "super" folder only 1. mkdir super2. cd super3. makestruct 4. cp init.struct

Dear developers and users I need to calculate work function of a semiconductor. I have not done this calculation before. I tried to complete the MgO example in the web (2016-work shop by prof. Blaha) and watched the video too. It explains the way for creating supercell nicely and I could
