IBRION has to be set to -1 and NSW to the number of supplied values ismear ) . Witrynatetrahedron method use ISMEAR=0. For relaxations in metalsalways use ISMEAR=1 and an appropriated SIGMA value (so that the entropy term is less than 1 meV per atom). Mind:Avoid to use ISMEAR0 for semiconductors and insulators, it might result in problems.
