 ## Description
-This project implements **PANKH** (Panel Analysis of uNsteady Kinematics of Hovering airfoils), a solver designed to study the aerodynamics of flapping foils. PANKH is a **low-fidelity solver** that solves the **Laplace equation** to determine the velocity distribution in the flow field. It enforces the **Neumann boundary condition** to satisfy the **no-penetration condition** (zero normal flux) on the airfoil surface.   The **unsteady Bernoulli equation** is then applied to compute the pressure difference across the airfoil, enabling the calculation of aerodynamic loads.
