Webb26 mars 2024 · The Richardson extrapolation method, also known as ‘ h 2 extrapolation’, ‘the deferred approach to the limit’ or ‘iterated extrapolation’, is a method for obtaining a higher-order estimate of the continuum value (value at zero grid spacing) from a series of lower-order discrete values. Webb1 mars 2024 · The key benefit of Richardson extrapolation is that we only need to know that the leading term in the asymptotic expansion is proportional to 1 / k, without the need to know the vector Δ. See an illustration below. Richardson extrapolation in two dimensions. The sequence is of the form x k = 1 k Δ 1 + ( − 1) k k 2 Δ 2.

Suppose you want to approximate a quantity Q, and you have available approximations Q(h) for h > 0. Typically, you know that this approximation is of a certain order, say richmont atlantaWebbA classical method for integrating ODEs with a high order of accuracy is the Fourth Order Runge Kutta (RK4) method. It is obtained from the Taylor series using similar approach we just discussed in the second-order method. This method uses four points , and . A weighted average of these is used to produce the approximation of the solution. richmont direct official site
