WebApr 22, 2006 · In the second part a number of numerical issues including implementation of high-order spatial schemes (dispersion-relation-preserving scheme and optimized prefactored compact scheme), fine-coarse interfaces under the AMR environment, stability analysis and filter/damping techniques are addressed. WebFeb 12, 2024 · The derivation of combined prefactored compact schemes for first and second order derivatives is described here, relying on the Fourier analysis of the original prefactored compact schemes. By this approach, the order of accuracy of the original schemes can be increased from sixth to eight, or from eight to tenth (depending on the …
