Computational simulation of one-dimensional waves with the Multigrid Method / Simulação computacional de ondas unidimensionais com o Método Multigrid
Autor: Sebastião Romero Franco, Marcio Augusto Villela Pinto, Maicon Felipe Malacarne
Publikováno v: Brazilian Journal of Development. 7:83763-83775
Several Engineering problems are modeled computationally, these simulations involve large systems, which are commonly difficult to solve. This paper deals with the simulation of one-dimensional waves, where the system resulting from the discretizatio

Subdomain method in time with waveform relaxation in space applied to the wave equation combined with the multigrid method
Autor: Maicon Felipe Malacarne, Marcio Augusto Villela Pinto, Sebastião Romero Franco
Publikováno v: Revista Internacional de Métodos Numéricos para Cálculo y Diseño en Ingeniería. 38
This work aims to evaluate a parallelizable approximate solution model for the wave equation. For that, we used the temporal sweep known as the Waveform Relaxation method to guarantee the parallelization in space. However, this technique has limitati

A multigrid waveform relaxation method for solving the poroelasticity equations
Autor: Sebastião Romero Franco, Marcio Augusto Villela Pinto, Francisco J. Gaspar, Carmen Rodrigo
Publikováno v: Compuational and Applied Mathematics, 37(4), 4805-4820
In this work, a multigrid waveform relaxation method is proposed for solving a collocated finite difference discretization of the linear Biot’s model. This gives rise to the first space–time multigrid solver for poroelasticity equations in the li

Multigrid method based on a space-time approach with standard coarsening for parabolic problems
Autor: Marcio Augusto Villela Pinto, Sebastião Romero Franco, Francisco J. Gaspar, Carmen Rodrigo
Publikováno v: Applied Mathematics and Computation, 317, 1339-1351
In this work, a space-time multigrid method which uses standard coarsening in both temporal and spatial domains and combines the use of different smoothers is proposed for the solution of the heat equation in one and two space dimensions. In particul
