    • A new Mean Preserving Moving Least Squares method for Arbitrary Order Finite Volume schemes 

      Ramírez, Luis; Edreira Marzoa, Laura; Couceiro, Iván; Ouro, Pablo; Nogueira, Xesús; Colominas, Ignasi (Elsevier, 2023)
      [Abstract:] In this paper we propose a new arbitrary-order Finite Volume method for the numerical solution of the Euler and Navier-Stokes equations on unstructured grids. Arbitrary order is achieved using a modified Moving ...

    • 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 ...

    • A simple model for mixing intuition and analysis 

      Katsikopoulos, Konstantinos V.; Egozcue, Martin; Fuentes García, Luis (Elsevier, 2022)
      [Abstract:] Firefighters, emergency paramedics, and airplane pilots are able to make correct judgments and choices in challenging situations of scarce information and time pressure. Experts often attribute such successes ...

    • 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 ...

    • An Arbitrary Lagrangian-Eulerian SPH-MLS Method for the Computation of Compressible Viscous Flows 

      Ramírez, Luis; Eirís, Antonio; Couceiro, Iván; París, José; Nogueira, Xesús (Elsevier, 2022)
      [Abstract] In this work we present a high-accurate discretization to solve the compressible Navier-Stokes equations using an Arbitrary Lagrangian-Eulerian meshless method (SPH-MLS), which can be seen as a general formulation ...
