Tool-box for parallel adaptive computations of 3-D convection-diffusion problems using domain decomposition
In this report we describe the tools that we have used, developed, and implemented in a computer system for simulation of flows in porous media. Our goal was to create a simulator that uses various tools and that is based on discretization by finite elements and finite volumes and uses efficient preconditioning iterative methods for the resulting large sparse system. Also important features are...
متن کاملCoupling parallel adaptive mesh refinement with a nonoverlapping domain decomposition solver
We study the effect of adaptive mesh refinement on a parallel domain decomposition solver of a linear system of algebraic equations. These concepts need to be combined within a parallel adaptive finite element software. A prototype implementation is presented for this purpose. It uses adaptive mesh refinement with one level of hanging nodes. Two and three-level versions of the Balancing Domain ...
متن کاملRecent Advances in Schwarz Waveform Moving Mesh Methods – A New Moving Subdomain Method
It is well accepted that the efficient solution of complex partial differential equations (PDEs) often requires methods which are adaptive in both space and time. In this paper we are interested in a class of spatially adaptive moving mesh (r-refinement) methods introduced in [9, 10, 12]. Our purpose is to introduce and explore a natural coupling of domain decomposition, Schwarz waveform relaxa...
متن کاملCFD PPLTMG Using A Posteriori Error Estimates and Domain Decomposition
Abstract. This two-part paper examines two approaches for mesh adaptation, using combinations of a posteriori error estimates and domain decomposition. In the first part, we consider a domain decomposition method applied to the generalized Stokes problem, with mesh adaptation in each subdomain using the a posteriori local error estimator as adaptation indicator. We apply domain decomposition wi...
متن کاملParallel Dynamic Mesh Generation and Domain Decomposition
The mapping of computations to parallel machines can be realized at the various data structures associated with the computations. In the case of PDE (Partial Differential Equations) based applications, we decided to fonnulate this problem at the discrete data structures of the underlying computation [Chri 91]. In this paper, we fonnulate and implement parallel mapping algorithms on distributed ...
