Application of Chimera with Hexahedral Blocks in Solar Meshes

The Chimera methodology of the DLR TAU solver is evaluated in this study for enhancing unstructured Solar grids. The discretization improvements using hexahedral blocks are demonstrated on a five-block grid of the NASA CRM and a two-block grid for the NASA Trapezoidal Wing. A vast potential for discretization improvements of Solar grids is found, but further assessments need to take into account the computational overhead still required by this non-native approach in TAU.
