        Abstract: I will review a current status of spin dynamical
        simulations within the framework of density functional theory. The
        importance of magnetic short range order in itinerant magnets will
        be emphasized with many relevant examples. The different ways of
        calculating the physical properties of magnets using direct
        simulations will be discussed. I will show in more detail the
        calculations of the exchange coupling using different band
        structure techniques. A comparison of different approaches, their
        physical and numerical accuracy will be given for completely
        different sets of magnetic systems. A first ab-initio explanation
        of the magnetism of Ni above the Curie temperature will be given.
