Several leaps forward for CFD simulations of hydrofoils

Hydrofoil simulation with NUMECA

While discussing with Xavier Guisnel from VPLP during the last marine session of the NUMECA User Meeting 2017, the idea of revising the hydrofoil simulation standards appeared to be a necessity. He mentioned that “the desired lift force should be an input and not just an output of the simulation”. But as CFD software developers, we know that if an input is not a boundary condition but a target value, the code should dynamically and automatically adapt to respect this value. For our case, the hydrofoil position should then be adapted to find a dynamic equilibrium position and reach the desired lift force. Internal debates started and the solution appeared quickly: the quasi-static approach, dedicated to hydrofoil, was born.
