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. -- Professor Laurence Marks (Laurie) Department of Materials Science and

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. Am 02.06.2023 um 15:16 schrieb Hamza Bouafia: Dear WIEN2k users, using r2SCAN (mgga) - relaxation can

Dear WIEN2k users, using r2SCAN (mgga) - relaxation can be done with mGGA with WIEN2k*? - For optimization, we perform init_mgga at the beginning or we have to change the script to launch it at each case.struct thank you in advance H Bouafia ___ Wien

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
