Re: [Wien] Different convergences in Non-SP and SP methods
I would argue that you did NOT find a difference between two calculations of the same thing. You only told the program to stop early. If you want to distiguish between states with a difference in energy smaller than the default 0.001 Ry, then you have to converge (with regard to ALL numeric parameters like RKmax, Emax, k-mesh ...) to a smaller energy. The same holds if you want to see if two solutions are the same: you can only tell if and that they are the same up to the precision you set as convergence criteria. Smaller energy differences are not significant - YOU told the program that they are not! --- Dr. Martin Pieper Karl-Franzens University Institute of Physics Universitätsplatz 5 A-8010 Graz Austria Tel.: +43-(0)316-380-8564 Am 03.01.2017 11:26, schrieb Abderrahmane Reggad: Thank you Mr delamora for your reply You have got a 0.003Ry/Cr difference between Cr ferromagnetic and antiferromagnetic structures But my problem is that I have found a difference between 2 equivalent calculations for the same structure: non magnetic Best regards -- Mr: A.Reggad Laboratoire de Génie Physique Université Ibn Khaldoun - Tiaret Adresse: BP 144 AL ATTAF AIN DEFLA Tel: +213(0)561861963 Algerie ___ Wien mailing list Wien@zeus.theochem.tuwien.ac.at http://zeus.theochem.tuwien.ac.at/mailman/listinfo/wien SEARCH the MAILING-LIST at: http://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/index.html ___ Wien mailing list Wien@zeus.theochem.tuwien.ac.at http://zeus.theochem.tuwien.ac.at/mailman/listinfo/wien SEARCH the MAILING-LIST at: http://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/index.html

If you need to use it, it is between w2w and wannier90, since it acts on case.eig. If you want to adapt the Fermi energy before w2w, you can do so by editing case.fermi.

Re: [Wien] Different convergences in Non-SP and SP methods
Thank you Dr Pieper for you answer According to the results with a difference of 0.001 Ry , can we considere the 2 calculations are the same ?

Re: [Wien] Different convergences in Non-SP and SP methods
From the plot you sent earlier the difference in these 2 calculations was 0.0001 Ry, not 0.001 !!?? Of course, with your default convergence criterium these 2 calculations are the same.
