This grid generation script creates unstructured CFD grids for rapid thermal protection system (TPS) damage aeroheating assessments. The existing manual solution is cumbersome, open to errors, and slow.The invention takes a large-scale geometry grid and its large-scale CFD solution, and creates a unstructured “patch” grid that models the TPS damage. The flow field boundary condition for the “patch” grid is then interpolated from the large-scale CFD solution. It speeds up the generation of CFD grids and solutions in the modeling of TPS damages and their aeroheating assessment. This process was successfully utilized during STS-134.
