The mesh adaptivity is used to improve the performance of the method. Although the results with the L-WENO method gets better as the mesh is refined, the mesh adaptation algorithm was able to improve the quality of the numerical approximation and reduce computational cost by refining and coarsening the computational mesh based on some specified criteria.enLegendre - Weighted Essentially Non-Oscillatory MethodAdaptive formulationMesh adaptationArticle
