A reduced-dissipation WENO scheme with automatic dissipation adjustment
Fernández-Fidalgo, Javier; Ramírez, Luis; Tsoutsanis, Panagiotis; Colominas, Ignasi; Nogueira, Xesús (Elsevier, 2020)[Abstract:] In this paper, we propose a novel modification to the WENO-family schemes to reduce its intrinsic dissipation. In this work, we focus on the WENO5 scheme, which is rewritten in terms of a central plus a dissipative ... -
An a posteriori, efficient, high-spectral resolution hybrid finite-difference method for compressible flows
Fernández-Fidalgo, Javier; Nogueira, Xesús; Ramírez, Luis; Colominas, Ignasi (Elsevier, 2018)[Abstract:] A high-order hybrid method consisting of a high-accurate explicit finite-difference scheme and a Weighted Essentially Non-Oscillatory (WENO) scheme is proposed in this article. Following this premise, two ... -
MLS-SPH-ALE: A Review of Meshless-FV Methods and a Unifying Formulation for Particle Discretizations
Eirís, Antonio; Ramírez, Luis; Couceiro, Iván; Fernández-Fidalgo, Javier; París, José; Nogueira, Xesús (Springer, 2023)[Abstract:] Mesh-based and particle methods were conceived as two different discretization strategies to solve partial differential equations. In the last two decades computational methods have diversified and a myriad of ... -
SPH-ALE Scheme for Weakly Compressible Viscous Flow with a Posteriori Stabilization
Eirís, Antonio; Ramírez, Luis; Fernández-Fidalgo, Javier; Couceiro, Iván; Nogueira, Xesús (MDPI, 2021)[Abstract] A highly accurate SPH method with a new stabilization paradigm has been introduced by the authors in a recent paper aimed to solve Euler equations for ideal gases. We present here the extension of the method to ... -
Very high-order method on immersed curved domains for finite difference schemes with regular Cartesian grids
Fernández-Fidalgo, Javier; Nogueira, Xesús; Ramírez, Luis; Colominas, Ignasi; Clain, Stéphane (Elsevier, 2020)[Abstract:] A new very high-order technique for solving conservation laws with curved boundary domains is proposed. A Finite Difference scheme on Cartesian grids is coupled with an original ghost cell method that provide ...
