Das Verfahren der Richardson-Extrapolation wurde von Lewis Fry Richardson (1881–1953) entwickelt. Es kann angewendet werden, wenn man bei der numerischen Lösung eines Problems aufgrund zweier verschiedener Diskretisierungen (mit den Schrittweiten und ) die Näherungen und für ein Problem hat, und diese Näherungen mit einem Verfahren -ter Ordnung berechnet worden sind. Sind diese Voraussetzungen erfüllt, so ist die Extrapolation Webb1 maj 2011 · It is shown that the use of Richardson extrapolation technique improves the ε-uniform accuracy of simple upwinding in the discrete supremum norm from N−1 ln N + Δt) to O (N−2 ln2 N +δt2), where N is the number of mesh-intervals in the spatial direction and Δt is the step size in the temporal direction.

Webb17 sep. 2024 · Using Richardson extrapolation is potentially a quick way to use these in an adaptive way, even if in the long run it would be nicer to derive a more specialized higher-order adaptive scheme. Yeah, and I think the interesting thing here is that it can be adaptive to reach a tolerance while still using the stability-bound step size. formica f8857Webb20 jan. 2024 · One of the most promising methods is Richardson extrapolation to the zero noise limit.

Other three techniques are applied to obtain a sixth-order solution on the fine grid, and thus give out three kinds of Richardson extrapolation-based sixth order compact computation methods. formica factory north shieldsWebb1 dec. 2008 · It is shown that the use of Richardson extrapolation technique improves the ε-uniform accuracy of simple upwinding in the discrete supremum norm from N−1 ln N + Δt) to O (N−2 ln2 N +δt2), where N is the number of mesh-intervals in the spatial direction and Δt is the step size in the temporal direction. different types of clinical psychologistWebb15 maj 2024 · In this paper, Modified Crank–Nicolson method is combined with Richardson extrapolation to solve the 1D heat equation.
