WitrynaIsmear -5 can get the forces wrong in metals which is problematic in relaxations. Instead of relaxtions you can also do a series of static calculations with variations in the structural parameters, of course, this can mean the need for a huge number of static calc to scan all possibilities with sufficient accuracy 2 votes 0 thanks WitrynaFor semiconductors or insulators use always tetrahedron method (ISMEAR=-5), if the cell is too large (or if you use only 1 or two k-points) use ISMEAR=0. For relaxations in metals always use ISMEAR=1 and an appropriated SIGMA value (the entropy term should less than 1 meV per atom).
