 Dear Prof. Dr. Blaha and WIEN2k users,

I've been using Wien2k since 4 months. I am a physics master's student,
calculating the magnetic and thermoelectric properties of quaternary
Heusler compounds. I have a question,

Energy and charge converged with PBEsol but not with PBEsol-mbj potential .

Xc potential : PBEsol - mbj
cc: 0.0001
ec: 0.00001
kmesh:20,20,20

Below I am sharing the results got after 100, 150 and 200 iterations.

    cycle 100 <>(Sat Apr 22 21:59:29 +03 2023) >(1/99 to go)
:ENERGY convergence:  0 0.00001 .0001018050000000
:CHARGE convergence:  0 0.0001 .0079100
>   energy in SCF NOT CONVERGED
>   stop

    cycle 150 <>(Sat Apr 22 23:24:49 +03 2023) >(1/49 to go)
:ENERGY convergence:  1 0.00001 .0000068950000000
:CHARGE convergence:  0 0.0001 .0032008
>   charge in SCF NOT CONVERGED
>   stop

    cyle 200 <>(Sun Apr 23 00:47:57 +03 2023) >(1/98 to go)
:ENERGY convergence:  1 0.00001 .0000027900000000
:CHARGE convergence:  0 0.0001 .0021041
>   charge in SCF NOT CONVERGED
>   stop

What should I do to get convergence? Please give your valuable suggestions

BestRegards,
Hülya
