4 ResultsThe FEM pipeline begins with pre‑processing, where the baseline rocket fin CAD geometry is imported into SimScale and assigned isotropic material properties such as elastic modulus, Poisson’s ratio, and yield strength. Kinematic constraints are applied at the fin‑to‑fuselage root, while aerodynamic loads are distributed across fin surfaces. A mesh independence study is conducted with coarse, medium, and fine grids to validate solver accuracy. Post‑processing evaluates Von Mises stress and displacement fields to identify stress concentrations and deflection zones. Finally, safety margins are calculated, ensuring the fin design maintains adequate factor of safety under maximum aerodynamic loads.
