cuIBM -- A GPU-accelerated Immersed Boundary Method
A projection-based immersed boundary method is dominated by sparse linear algebra routines. Using the open-source Cusp library, we observe a speedup (with respect to a single cpu core) which reflects the constraints of a bandwidth-dominated problem on the gpu. Nevertheless, gpus offer the capacity to solve large problems on commodity hardware. This work includes validation and a convergence stu...
متن کاملA discontinuous-Galerkin-based immersed boundary method
A numerical method to approximate partial differential equations on meshes that do not conform to the domain boundaries is introduced. The proposed method is conceptually simple and free of userdefined parameters. Starting with a conforming finite element mesh, the key ingredient is to switch those elements intersected by the Dirichlet boundary to a discontinuous-Galerkin approximation and impo...
متن کاملThe immersed boundary method : a
In this paper we consider a modiication of the immersed boundary method based on a nite element approximation of the uid. Besides some theoretical considerations, we present two dimensional numerical examples which connrm the good behavior of the computed solutions.
متن کاملFrom Immersed Boundary Method to Immersed Continuum Method
The objective of this paper is to present an overview of the newly proposed immersed continuum method in conjunction with the traditional treatment of fluidstructure interaction problems, the immersed boundary method, the extended immersed boundary method, the immersed finite element method, and the fictitious domain method. In particular, the key aspects of the immersed continuum method in com...
متن کاملOptimal convergence of a discontinuous-Galerkin-based immersed boundary method
We prove the optimal convergence of a discontinous-Galerkin-based immersed boundary method introduced earlier [Lew and Buscaglia, 2008]. By switching to a discontinuous Galerkin discretization near the boundary, this method overcomes the suboptimal convergence rate that may arise in immersed boundary methods when strongly imposing essential boundary conditions. We consider a model Poisson’s pro...
