Parallel Computing for Reacting Flows Using Adaptive Grid Refinement
The paper reports on the parallelisation of the computational code for modelling turbulent combustion in large industrial 3D glass melting furnaces. Domain decomposition is used to perform the parallelisation. Performance optimisation is examined, to both speed up the code as well as to improve convergence. Local grid refinement is discussed using several different refinement criteria. The nume...
متن کاملRelativistic Hydrodynamic Flows Using Spatial and Temporal Adaptive Structured Mesh Refinement
Astrophysical relativistic flow problems require high resolution three-dimensional numerical simulations. In this paper, we describe a new parallel three-dimensional code for simulations of special relativistic hydrodynamics (SRHD) using both spatially and temporally structured adaptive mesh refinement (AMR). We used the method of lines to discretize the SRHD equations spatially and a total var...
متن کاملAMRA: An Adaptive Mesh Refinement Hydrodynamic Code for Astrophysics
Implementation details and test cases of a newly developed hydrodynamic code, amra, are presented. The numerical scheme exploits the adaptive mesh refinement technique coupled to modern high-resolution schemes which are suitable for relativistic and non-relativistic flows. Various physical processes are incorporated using the operator splitting approach, and include self-gravity, nuclear burnin...
متن کاملAGRIF: Adaptive grid refinement in Fortran
Adaptive grid refinement in Fortran (AGRIF) is a Fortran90 package for the integration of adaptive mesh refinement (AMR) features within existing finite difference codes. The package first provides model-independent Fortran90 procedures containing the different operations in an AMR process: time integration of grid hierarchy, clustering, interpolations, updates, etc. The package then creates th...
متن کاملComputations of Unsteady Viscous Compressible Flows Using Adaptive Mesh Refinement in Curvilinear Body-Fitted Grid Systems
A methodology for accurate ana efficient simulation of unsteady, compressible flows is presented. The cornerstones of the methodology are a. special discretization of the N avier-Stokes equa.tions on structured bodyfitted grid systems and an efficient solution-adaptive mesh refinement technique for structured grids. The discretization employs an explicit multidimensional upwind scheme for the i...
