[Wien] Convergence problem in mbj potential calculation

[Fecher, Gerhard]

No answer possible, without knowing your convergence criteria 
are they just too tight ?

Number of k-points too small ? rkmax ? number of atoms ?

"I think the problem, to be quite honest with you,
is that you have never actually known what the question is."

Betreff: [Wien] Convergence problem in mbj potential calculation

Dear wien2k users,

                      I am trying to simulate DOS of a semiconducting material using mbj potential. It has run for 230 cycles now. Also, from cycle 210 to 230 the charge & energy convergence remain stuck at a single value. what should I do now?...should I change the mixing parameter or should I just wait?

Any response in this regard will be helpful for us.

with regards,
