flow5 is an open-source aerodynamic simulation application designed for preliminary analysis of wings, aircraft, hydrofoils, and sails. As the successor to XFLR5, it combines potential flow solvers with integrated preprocessing and postprocessing tools. Engineers can construct aerodynamic geometries and evaluate their performance under different flow conditions. Its XFoil integration supports airfoil generation and two-dimensional polar calculations. Three-dimensional aircraft analysis includes viscous drag estimation and aerodynamic polar generation. The software supports importing geometry from STL, STEP, and XML files, including complex fuselage shapes. Automated calculations are available through a programming API with batch processing capabilities. flow5 emphasizes efficient modeling and reliable preliminary design evaluation.
