CFD Mesh Generation for Rocket Body with Grid Fins

Generated a surface and volume mesh in ANSYS around a rocket booster body fitted with grid fins, in preparation for CFD analysis of aerodynamic control and drag during descent/re-entry. The mesh uses a refined unstructured tetrahedral grid concentrated around the fin surfaces and body junctions to accurately capture local flow gradients, while coarsening toward the far-field domain to balance accuracy with computational cost. This mesh forms the pre-processing foundation for simulating fin-induced aerodynamic forces and flow interaction along the booster body.
