[QE-users] Blue moon ensemble calculations in quantum espresso

2022-12-12 Thread Payal Chaudhary
Dear all, I had a question about running blue moon calculations with Quantum Espresso. To get the free energy profile along a reaction coordinate, we can run several constrained MD calculations and use the blue moon ensemble averages to get free energy gradients. These gradients can then be

[QE-users] pp.x: iflag=1 for the plot_number=0

2022-12-12 Thread Aleksandra Oranskaia
Dear users and developers, Is it possible to plot 1D-distribution of the charge density with pp.x? Looks like for plot_number=0 ifrag cannot be anything than 3. With the following input only myinput.rho is generated. (I tried the latest QE version.) prefix = myinput filplot = myinput.rho

[QE-users] Correct procedure: CIF to slab with convergence tests

2022-12-12 Thread Léon Luntadila Lufungula
Dear QE users, I want to construct an anatase (101) slab starting from the experimental CIF file of anatase (obtained from the American Mineralogist Crystal Structure Database) but I am unsure of the correct procedure with the associated convergence tests of the parameters of the QE

So you start from the scratch of the index notation: XC-000i-000i-000i-000i-000i-000i The first slot is for LDA-exchange, the second LDA correlation, the third GGA exchange, then GGA correlation, MGGA exchange and MGGA correlation. Now, you want to use the MGGA_C_M06 (with no exchange?) which has

Hi, Fabrizio I found the following information in the link you provided, MGGA_C_M06(id=235): Minnesota M06 correlation functional However, the calculation does work when I use input_dft="MGGA_C_M06" or input_dft="id=235" In the user guide, I also found the following description, but where

Dear Jibiao, I stress the following lines from the user guide: The complete list of libxc functionals (and their IDs) is available at: https://www.tddft.org/programs/libxc/functionals/ So you can find there the IDs to put in the index notation. Cheers, Fabrizio
