MultiSurface for Hydrofoil Design & Analysis

hydrofoil design and  analysis

MultiSurface Aerodynamics is used by designers and engineers to solve problems associated with hydrofoil product development. It is used to accurately compute lift and drag forces, longitudinal stability, screen for cavitation and produce 3D .STL files for manufacturing prototypes. MultiSurface Aerodynamics includes a powerful airfoil analysis tool that is used to analyze cross sectional shapes to improve the efficiency of the hydrofoil.
