As an addendum, the only cases I know of when PRATT is relevant are: 1. With mBJ at the start (although I wonder about this) 2. With really badly posed problems, although it may not be safe and even then should only be used for a few iterations 3. In some cases "echo 0.025 > .pratt"

1. CHARGE CONVERGENCE: I know this has been discussed before, but it seems it didn't change in Wien2k_18. Here is a typical example of the charge convergence history of the last few iterations of FM+SOC (ferromagnetic + spin orbit coupling) calculation: :ENERGY convergence:  0 0.0001

Dear All, Sorry for a longer email, but couple of things have accumulated. I have three questions, one on charge convergence, another one on setting the limits in case.inso and case.in1c to avoid large vector files, and a last one on some expert advice on how to converge FM+SOC calculations
