Abstract
We present a new algorithm for interpolation of static current-free magnetic fields based on the use of specialized fourth-degree vector polynomial functions (Maxwell elements) which solve the static current-free Maxwell equations. This method provides sufficient accuracy for the demands of stellarator applications and retains a great speed advantage over direct Biot-Savart calculation of the fields.
