Curve Fitting Estimating Method for Solving the Open Domain Problem

摘要

This paper presents Curve Fitting Estimating Method (CFEM) to solve open domain problem: first using FEM to calculate a set of closed domains extended step-by-step properly and then use the curve fitting method to evaluate the real solver of the open domain. An example that using this method to solve the open-domain field distribution of a square coil is given. Compared with Biot-Savart solutions and values of Asymptotic Boundary Condition (ABCs), the result agrees within a few percent with Biot-Savart solutions.
