Explicit high-order numerical schemes are proposed for the accurate computation of multiple-scale problems and for the implementation of boundary conditions. Specific high-order node-centered finite differences and selective filters removing grid-to-grid oscillations are first designed for the discretization of the buffer region between a Dx-grid domain and(More)
A noncentered interpolation technique has been constructed to perform simulations using overlapping grids for complex geometries. High-order centered Lagrange polynomial interpolations and interpolations optimized in the Fourier space are first generalized to the noncentered case. These noncentered interpolations either generate significant dispersion(More)
