In the first email from Boufia, does "every case" refer to changing the
lattice parameters? That only requires the total energy so works with mGGA.
It is internal position which cannot be relaxed currently, i.e. -min.

No, relaxation is not possible as forces with mGGA are not implemented.
You only need init_mgga once (or most likely twice) in a directory. It
does not do anything with the struct files.

Dear WIEN2k users,

- For optimization, we perform init_mgga at the beginning or we have to

Dear Shalika,
Alternatively, you may use the package OrthoOpt
available at
http://susi.theochem.tuwien.ac.at/reg_user/unsupported/OrthoOpt/
This package automatically determines the orthorhombic or monoclinic
lattice parameters a,b,c (the monoclinic angle is fixed).
You can try this for

Dear Wien Users,
I try to do relaxation with the " min_lapw -p " command like in UG.
(Alternatively you can use "min_lapw -p" which is identical to:
min_lapw -j ‘‘run_lapw -I -fc 1 -p’’)

Indeed, forces are not implemented for hybrid functionals. Also not for
SOC. So, no relaxation of atomic positions is possible.

Probably nobody can help, unless you provide your case.struct file. More than
likely, the errors are caused by a problem with your case.struct.

Thank you for your replied all. It helps me a lot.
I usually only calculate magnetic properties, and it seems like that the
relaxation does not affect the magnetic properties much (at least the
material I calculate now).
I am wondering if the other properties are affected a lot more.

Jihoon, it depends on the sensitivity of the calculations. I generally always
use the experimental lattice constants, and then relax the internal coordinates
