[Pw_forum] About using plotproj.x

2016-09-03 Thread Abdullah N. Albarakati
Dear QE experts, plotproj.x needs input files and parameters which I do not know how to provide them. Below is what it ask for " This small program is used to select the band eigenvalues whose ! wavefunctions projected on atomic wavefunctions have projections larger ! than a given threshold.

[Pw_forum] Calculation of Gibbs free energy for NO2 gas

2016-09-03 Thread Rolly Ng
Dear QE experts, I am trying to calculate the Gibbs free energy of a NO2 gas molecule via the following steps, 1) pw.x to "relax" a NO2 gas molecule in a cube box 2) pw.x to calculate the "scf" energy with the relaxed NO2 gas geometry, using only 1 K-point at 0 0 0. (NO2_scf.in) 3) ph.x

Dear Santosh, Can you try to plot using plotband.x ? It does the job properly, if you have problem of overlapping line using in the bands calculation noroverlap= .true., you will also resolve that problem But can you try to use plotband.x ?? Il 03/09/2016 10:28, Santosh

Dear Ghadiyali Mohammed Kader, alat is what you have defined as either the parameter A or the parameter celldm(1) under the namelist. celldm(1) is in bohr and A is in angstrom. If you have celldm(1): multiply the entries in CELL_PARAMETERS by celldm(1) remove the parameter celldm(1) from the

Dear All, It would be very helpful if someone can inform me as how to convert or define a crystal structure in the combination of ibrav = 0 and CELL_PARAMETERS in bhor rather than the normally used combination of ibrav = 0 and CELL_PARAMETERS in alat. As I what to use phononpy for the

Thanks for reply, First of all, I am new to this forum and I couldn't see reply until searching with similar Topic :). Thanks for the reply. Looks like I made lots of mistake!!! Can anybody please give me the procedure to get bands structrue with some example. so that I can follow it. Thank
