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 ... -
A short note on a 3D spectral analysis for turbulent flows on unstructured meshes
Tsoutsanis, Panagiotis; Nogueira, Xesús; Fu, Lin (Elsevier, 2023)[Abstract:] We propose two techniques for computing the energy spectra for 3D unstructured meshes that are consistent across different element types. These techniques can be particularly useful when assessing the dissipation ... -
UCNS3D: An open-source high-order finite-volume unstructured CFD solver
Antoniadis, Antonis F.; Drikakis, Dimitris; Farmakis, Pericles S.; Fu, Lin; Kokkinakis, Ioannis; Nogueira, Xesús; Silva, Paulo A.S.F.; Skote, Martin; Titarev, Vladimir; Tsoutsanis, Panagiotis (Elsevier, 2022)[Abstract:] UCNS3D is an open-source computational solver for compressible flows on unstructured meshes. State-of-the-art high-order methods and their associated benefits can now be implemented for industrial-scale CFD ... -
WENO Schemes on Unstructured Meshes Using a Relaxed a Posteriori MOOD Limiting Approach
Farmakis, Pericles S.; Tsoutsanis, Panagiotis; Nogueira, Xesús (Elsevier, 2020)[Abstract] In this paper a relaxed formulation of the a posteriori Multi-dimensional Optimal Order Detection (MOOD) limiting approach is introduced for weighted essentially non-oscillatory (WENO) finite volume schemes on ...
