چکیده
The long computation times required for fluid dynamics simulations (CFD) has lead the industry to look for some alternatives to boost high performance computing (HPC). This paper is focused on the acceleration of fluid dynamics simulations for industrial complex configurations using modern graphics cards (GPUs) that exhibits a substantial parallel architecture. First, some general facts about general purpose programming with GPUs (GPGPU) are presented. Then, we explain the implementation of a CFD solver for the resolution of 2D Euler equations on unstructured grids and some problems related to the parallelization of this algorithm. Finally, two approaches based on hybrid CPU-GPU, and full GPU implementations are compared.

A New Implicit Dissipation Term for Solving 3D Euler Equations on Unstructured Grids by GMRES+LU-SGS Scheme
Due to improvements in computational resources, interest has recently increased in using implicit scheme for solving flow equations on 3D unstructured grids. However, most of the implicit schemes produce greater numerical diffusion error than their corresponding explicit schemes. This stems from the fact that in linearizing implicit fluxes, it is conventional to replace the Jacobian matrix in t...

متن کاملPyFR: An Open Source Framework for Solving Advection-Diffusion Type Problems on Streaming Architectures using the Flux Reconstruction Approach
High-order numerical methods for unstructured grids combine the superior accuracy of high-order spectral or finite difference methods with the geometric flexibility of low-order finite volume or finite element schemes. The Flux Reconstruction (FR) approach unifies various high-order schemes for unstructured grids within a single framework. Additionally, the FR approach exhibits a significant de...
متن کاملAgglomeration Multigrid and Parallel Processing for the Numerical Solution of the Euler Equations on 2d and 3d Unstructured Grids
Abstract. This paper aims at coupling two known CFD techniques, namely multigrid and parallelization, in an existing Euler equations solver for 2D and 3D unstructured grids. The solver is based on a time-marching formulation for the high-subsonic/transonic flow equations and a pointwise implicit solution algorithm. The gain from the combined use of multigrid and parallelization is the reduction...

We present a new formulation of three-dimensional central finite volume methods on unstructured staggered grids for solving systems of hyperbolic equations. Based on the Lax-Friedrichs and Nessyahu-Tadmor one-dimensional central finite difference schemes, the numerical methods we propose involve a staggered grids in order to avoid solving Riemann problems at cell interfaces. The cells are baryc...
