[Octopus-users] how to improve convergence with oep_x?

[Alberto Castro]

Hi,

Maybe it does not help, but are you mixing the density or the
potential? It should be the potential; try setting "MixField =
potential" (newer versions of the code set this as default for OEP or
MGGA calculations, but it did not happen before... Also, previously
this variable was called "TypeOfMixing")

Cheers, Alberto
