      abstract     = {We present simulation results on the structure and dynamics
                      of micromagnetic point singularities with atomistic
                      resolution. This is achieved by embedding an atomistic
                      computational region into a standard micromagnetic
                      algorithm. Several length scales are bridged by means of an
                      adaptive mesh refinement and a seamless coupling between the
                      continuum theory and a Heisenberg formulation for the
                      atomistic region. The code operates on graphical processing
                      units and is able to detect and track the position of
                      strongly inhomogeneous magnetic regions. This enables us to
                      reliably simulate the dynamics of Bloch points, which means
                      that a fundamental class of micromagnetic switching
                      processes can be analyzed with unprecedented accuracy. We
                      test the code by comparing it with established results and
                      present its functionality with the example of a simulated
                      field-driven Bloch-point motion in a soft-magnetic
                      cylinder.},
