Numerical Analysis and Safety Design of Grounding Systems in Underground Compact Substations
(Elsevier, 2022)
[Abstract] This paper presents a mathematical and numerical formulation to design and analyze grounding systems in underground electrical substations. The developed approach is based on the well known Maxwell’s Equations. ...
A new Mean Preserving Moving Least Squares method for Arbitrary Order Finite Volume schemes
(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 ...
An Arbitrary Lagrangian-Eulerian SPH-MLS Method for the Computation of Compressible Viscous Flows
(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 ...
Computer software for analysis and design optimization of power transmission structures by simulated annealing and sensitivity analysis
(Springer, 2021)
[Abstract:] This paper presents a computer software for the optimization of power transmission structures. The software employs a modified version of the Simulated Annealing algorithm that has been proven effective in large ...
Optimization of Offshore Steel Jackets: Review and Proposal of a New Formulation for Time-Dependent Constraints
(Springer, 2020)
[Abstract:] In this work, a methodology for the optimization of offshore wind turbine substructures (jacket type) is presented. The use of a coupled model allows for capturing the full dynamic interaction between all the ...
Estimation of long-term fatigue damage of fixed substructures using fully-coupled models and non-linear dynamic analysis
(Elsevier, 2020)
[Abstract:] Typical industry models for Offshore Wind Turbines with fixed substructures are based on decoupled models between the wind turbine and the substructure. It is proved that the complete dynamic response of the ...
MLS-SPH-ALE: A Review of Meshless-FV Methods and a Unifying Formulation for Particle Discretizations
(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
(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 ...
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 ...
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 ...
