A Modified Adaptive Improved Mapped WENO Method [PDF]
Communications in Computational Physics, 2021 We propose a new family of mapped WENO schemes by using several adaptive control functions and a smoothing approximation of the signum function. The proposed schemes admit an extensive permitted range of the parameters in the mapping functions. Consequently, they have the capacity to achieve optimal convergence rates, even near critical points ...

WENO schemes on arbitrary mixed-element unstructured meshes in three space dimensions [PDF]
, 2010 The paper extends weighted essentially non-oscillatory (WENO) methods to three dimensional mixed-element unstructured meshes, comprising tetrahedral, hexahedral, prismatic and pyramidal elements. Numerical results illustrate the convergence rates and non-

Computers & Fluids, 2018 This work is dedicated to the development and comparison of WENO-type reconstructions for hyperbolic systems of balance laws. We are particularly interested in high order shock capturing non-oscillatory schemes with uniform accuracy within each cell and low spurious effects.

An improved WENO-Z scheme with symmetry-preserving mapping
Advances in Aerodynamics, 2020 Since the classical weighted essentially non-oscillatory (WENO) scheme is proposed, various improved versions have been developed, and a typical one is the WENO-Z scheme.

Discontinuity Preserving Scheme [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2020 Non-linear schemes are widely used in high-speed flows to capture the discontinuities present in the solution. Limiters and weighted essentially non-oscillatory schemes (WENO) are the most common non-linear numerical schemes.

New Weighting Strategies for Weno Schemes
, 2023 In this article, we propose a modified convex combination of the polynomial reconstructions of odd-order WENO schemes to maintain the central substencil prevalence over the lateral ones in all parts of the solution. New "centered" versions of the classical WENO-Z and its less dissipative counterpart, WENO-Z+, are defined through very simple ...
