Using global interpolation to evaluate the Biot−Savart integral for deformable elliptical Gaussian vortex elements
This paper introduces a new method for approximating the Biot-Savart integral for elliptical Gaussian functions using high-order interpolation and compares it to an existing method based on small aspect ratio asymptotics. The new evaluation technique uses polynomials to approximate the kernel corres...
