      abstract     = {The article presents a general-purpose hybrid
                      finite-element/boundary-element method (FEM/BEM) to
                      calculate magnetostatic fields generated by stationary
                      electric currents. The efficiency of this code lies in its
                      ability to simulate Oersted fields in complex geometries
                      with non-uniform current density distributions. As a
                      precursor to the calculation of the Oersted field, an FEM
                      algorithm is employed to calculate the electric current
                      density distribution. The accuracy of the code is confirmed
                      by comparison with analytic results. Two examples show how
                      this method provides important numerical data that can be
                      directly plugged into micromagnetic simulations: The current
                      density distribution in a thin magnetic strip with a notch,
                      and the Oersted field in a three-dimensional contact
                      geometry; similar to the type commonly used in spin-torque
                      driven nano-oscillators. It is argued that a precise
                      calculation of both, the Oersted field and the current
                      density distribution, is essential for a reliable simulation
                      of current-driven micromagnetic processes.},
