Of course, somebody "understanding" WIEN2k can do it, but it requires
"tricks" that are not recommended for a regular user.
So the general rule is: don't mix spin-polarized and unpolarized
calculations in one directory.

Hello again
I have just found where it's mentionned that we can do a spin polarized
calculation from a non spin polarized calculation but for another code.
" Often it is, however, faster first to perform a self-consistent NM
calculation and then using this to start the spin-polarized
First I have to thank Pr Blaha for the clarification and I am sorry the
wrong statement and I have to correct it as I have found it in the book "
Planewaves Pseudopotentials and the LAPW Method" at the page 81 which the
author stated " Further, the FSM procedure is quite useful in obtaining

Rather than removing the Broyden files, an alternative is to inject a Pratt
step. To do this, look at the values of the GREED (i.e. grep :MIX case.scf)
and chose a moderately small number, e.g. 0.025. Then do "echo 0.025 >
.pratt". This injects a single step without losing the memory.

I don't know from where you have this recipe, but it does not work. From
a non-spinpolarized calc. you cannot go to a spin-polarized solution.
For difficult spin-polarized calculations you may need more than the 40
default iterations. Continue and specify more iterations (-i 80 or more).
Hello wien users
When we encounter a problem of converge in a spin polarized calculation
there is a solution which states that we do a non spin polarized
calculation which is known with its faster convergence and using the new
densities as starting densities for a new spin polarized calculation.
