Title:A critical evaluation of theresolution properties of b-spline and compact finite difference methods
Author(s):Kwok, Wai Yip; Moser, Robert D.; Jimenez, Javier
Fourier Analysis
Uniform And Non-uniform Mesh/grid
Abstract:Resolution properties of B-spline and compact finite difference schemes are compared using Fourier analysis in periodic domains, and tests based on solution of the wave and heat equations in finite domains, with uniform and non-uniform grids. Results show that compact finite difference schemes have a higher convergence rate and in some cases better resolution. However, B-spline schemes have a more straightforward and robust formulation, particularly near boundaries on non-uniform meshes.
