En este trabajo se presenta una comparación de la solución numérica de la ecuación de Helmholtz utilizando el método de elementos finitos Galerkin Discontinuo Local (LDG) con varias condiciones de contorno absorbentes ...

The spatial discretization of the unsteady incompressible Navier-Stokes equations is stated as a system of Differential Algebraic Equations (DAEs), corresponding to the conservation of momentum equation plus the constraint ...

A p-adaptive hybridizable discontinuous Galerkin method for the solution of wave problems is presented in a challenging engineering problem. Moreover, its performance is compared with a high-order continuous Galerkin. The ...

Imposing essential boundary conditions is a key issue in mesh-free methods. The mesh-free interpolation does not verify the Kronecker delta property and, therefore, the imposition of prescribed values is not as straightforward ...

La ingeniería computacional se ha consolidado ya como una disciplina horizontal en el ámbito de la ingeniería civil. La modelización numérica es, cada vez más, una alternativa para el cálculo y diseño en inge niería a los ...

The aim of this chapter is to provide an in-depth presentation and survey of meshfree particle methods. Several particle approximations are reviewed; the SPH method, corrected gradient methods and the moving least squares ...
