      abstract     = {The automatic grid generation on high performance computers
                      is a challenging task under the restriction of computational
                      power and memory availability. The increasing demand for
                      high grid resolutions to simulate complex flow
                      configurations necessitates parallel grid generation on
                      multicore machines with distributed memory. In this study, a
                      new robust algorithm to automatically generate hierarchical
                      Cartesian meshes on distributed multicore HPC systems with
                      multiple levels of refinement is presented. The number of
                      cells is only restricted by the number of available cores
                      and memory. The algorithm efficiently realizes a
                      computational domain decompositioning for an arbitrary
                      number of cores based on a Hilbert curve. The grids are
                      efficiently stored and accessed via a high capacity parallel
                      I/O method. The efficiency of the approach is demonstrated
                      by considering human nasal cavity and internal combustion
                      engine flow problems.},
