Abstract :
Two-point and three-point are used to improve the accuracy of numerical results for electromagnetic applications. When applied to a sequence of results obtained with conventional h-refinement, extrapolation procedures permit an estimate of the quantity of interest in the limit as h tends to zero. Three-point procedures also provide an estimate of the rate at which the error decreases, and can consequently improve confidence in the numerical results.
