Why do computer methods for grounding analysis produce anomalous results?
(IEEE Power Engineering Society, 2003)
[Abstract] Grounding systems are designed to guarantee personal security, protection of equipments and continuity of power
supply. Hence, engineers must compute the equivalent resistance of the system and the potential ...
Sobre el empleo de técnicas de mínimos cuadrados móviles en el desarrollo de métodos de alta resolución de volúmenes finitos en mallas no estructuradas. Aplicación a problemas de flujo comprensible
(2005)
En este artículo se propone la combinación de aproximaciones por mínimos
cuadrados móviles y esquemas upwind de volúmenes finitos, aplicados a problemas de flujo
compresible en mallas no estructuradas. La construcción ...
A Well-Balanced SPH-ALE Scheme for Shallow Water Applications
(Springer, 2021)
[Abstract] In this work, a new discretization of the source term of the shallow water equations with non-flat bottom geometry is proposed to obtain a well-balanced scheme. A Smoothed Particle Hydrodynamics Arbitrary ...
Stabilization of numerical formulations for convective-diffussive transport problems
(The International Center of Numerical Methods in Engineering, 2000)
[Abstract] Numerical simulation in Fluid Mechanics is an extremely difficult task, wich complexity increases exponentially as the velocity of the fluid becomes higher. In particular, it is know that serious troubles are ...
Topology optimization of structures considering minimum weight and stress constraints by using the Overweight Approach
(Elsevier, 2022)
[Abstract:] In this paper, a new method for structural topology optimization considering minimum weight and local stress constraints is proposed. For this purpose, the Overweight Approach, an improvement of the so-called ...
A very accurate Arbitrary Lagrangian–Eulerian meshless method for Computational Aeroacoustics
(Elsevier, 2018)
[Abstract:] In this work, we propose a new meshless approach based on a Galerkin discretization of a set of conservation equations on an Arbitrary Lagrangian–Eulerian framework. In particular, we solve the Linearized Euler ...
A Higher‑Order Chimera Method for Finite Volume Schemes
(Springer, 2018)
[Abstract:] In this work a higher-order accurate finite volume method for the resolution of the Euler/Navier–Stokes equations using Chimera grid techniques is presented. The formulation is based on the use of Moving Least ...
An a posteriori, efficient, high-spectral resolution hybrid finite-difference method for compressible flows
(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 ...
A reduced-dissipation WENO scheme with automatic dissipation adjustment
(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 ...
Computational modelling suggests complex interactions between interstitial flow and tumour angiogenesis
(Royal Society, 2018)
[Abstract:] Angiogenesis, the growth of capillaries from pre-existing ones, plays a key role in cancer progression. Tumours release tumour angiogenic factors (TAFs) into the extracellular matrix (ECM) that trigger angiogenesis ...
