[Pw_forum] unexpected force_symmorphic behavior with explicit k grid

2012-06-21 Thread Giovanni Pizzi
Dear Paolo, thanks for your answer. Indeed, I am using Yambo which requires that flag. The point is that Andrea Marini and I are working on a Wannier90 interface for Yambo. While for the generation of the automatic grids the increased number of k points is perfectly ok, the problem arises when w

[Pw_forum] projwfc.x error with spin orbit

2012-06-21 Thread Virk Naunidh
Dear Paolo, Thanks for your suggestion. Have tried what you suggested, have run the calculation on a cluster (in parallel), and on a single local machine. The same error is reproduced. -- Naunidh Virk EPFL, ITP, Lausanne, CH. De : pw_forum-bounces at pws

[Pw_forum] k-point-path

2012-06-21 Thread DENIS MAGERO
Hallo payam. Im not sure whether I understood your question correctly but incase you need the k point path for high symmetry points this is what you should do; Check on any paper that has dealt with your material and you can get the points of high symmetry from there, probably the band structure wi

Alternatively, you could use the website:http://www.cryst.ehu.es/cryst/get_kvec.html to get the coordinates of the high symmetry k-points. Regards, Nandan. On Thu, Jun 21, 2012 at 6:31 AM, DENIS MAGERO wrote: > Hallo payam. Im not sure whether I understood your question correctly > but incase y

[Pw_forum] SCF Correction Too Large ...

2012-06-21 Thread Vic Bermudez
Hello, I'm doing a series of geometry optimizations and getting the following message at the end of some of the cycles: "SCF correction compared to forces is large: reduce conv_thr to get better values" Nevertheless, I do get geometry convergence. My convergence thresholds for energy cha
