Flight Reconstruction of the Starship Landing Maneuver using OVERFLOW

This presentation details the configuration of the OVERFLOW CFD solver for reconstructing the landing trajectory of the Starship vehicle. Simulation fidelity encompasses moving flaps, gimbaling engines, and time-varying thrust. Time-accurate solutions employ Delayed Detached-Eddy Simulation (DDES) together with low-dissipation, fifth-order-accurate numerical schemes to resolve the unsteady, low-speed aerodynamics. The gridding and hole-cutting strategies, vehicle motion setup, and boundary conditions for time-varying thrust are presented, along with representative results for aerodynamic coefficients and flow-field visualizations.
