Permanent magnets are key elements for power conversion for sustainable technologies. The increasing demand of permanent magnets for wind power, hybrid and electric vehicles led to a search for novel permanent magnets with reduced amount of (heavy) rare earth elements. Computer simulation give a basic understanding of the magnetization reversal process at the nano- and microscale that determine the energy density product of a permanent magnet.
In my talk I will give a short introduction into the finite element simulation of the properties of permanent magnets. I will discuss the computational challenges for modeling magnets on massively parallel systems including super computers or graphical processing units. Finally, I will address several concepts for rare earth reduced magnets.
