[Wien] Convergence problem in mbj potential calculation

I have said this before, but it is worth repeating: the most common reason
a calculation does not converge is because the structure/model is
unphysical/unchemical. Your Ti-O bonds are too long, the structure is
"obviously" wrong.

Scientific rigor is not optional. What is the R-factor? Are the temperature
factors sane? Is there an independent​ measurement of the composition, e.g.
ICP? Have you measured that it is FM?

Indeed, your compound is also metallic already with PBE, this you did not
tell when I asked about PBE.
Also, the PBE does not result in a ferromagnetic state, I guess ?
