Study of interpolation methods for high-accuracy computations on overlapping grids

► High-accuracy Lagrange or optimized interpolation schemes are investigated. ► A DRP-type optimization is advantageous to deal with high-frequency phenomena. ► An interpolation stencil with less points than the discretization can be acceptable. ► The choice of an interpolation for multidimensional...
