Parallelisation of CFD methods for multi-physics problems

The focus of this paper is on the parallel computing aspects of multi-physics CFD methods and the implications for the design of a CFD framework encompassing mesh-based and particle-based approaches. In the first part of the paper, the shared-memory parallelisation of a multi-block, structured CFD is described and the parallel performance of...

Level set based parallel computations of unsteady free surface flows

The simulation of free surface flow is a computationally demanding task. Real life simulations require often the treatment of unstructured grids to capture the complex geometries and the use of parallel supercomputers for the efficient solution. For that aim, we have developed an efficient parallel free surface flow solver based on a full...

A High Scalability Parallel Algebraic Multigrid Solver

This paper deals with the implementation and performance analysis of a parallel Algebraic Multigrid Solver (pAMG) for a finite volume unstructured CFD code. The parallelization of the solver is based on the domain decomposition approach using the single program multiple data paradigm. The Message passing interface Library (MPI) is used for...

3D visualization of extra large data arrays by means of scientificVR® visualizer

Visualization of data is nowadays an indispensable part of scientific research and effect analysis practically in any field of natural sciences. Graphic presentation of the results in the form of color lay-outs or functional dependence diagrams makes it considerably easier to perceive new information and contributes to a more sophisticated and...

Automatic parallelization of finite element CFD code using HPC middleware

Computational fluid analysis requires huge amounts of computational resources. However, for the usual developer, parallelization is difficult as it requires special programming skills. In this study, the “HPC Middleware” is employed, which supports parallelization and optimizations for easily developing parallel code. The parallel efficiency of...

3D parallel spectral computations of fan noise

A three-dimensional computational aeroacoustics code has been developed for the simulation of tone noise generated by turbofan engine inlets. The code is based on the linearized Euler equations, rewritten in terms of acoustic potential and solved in the frequency domain. Spatial discretization is performed using a spectral element method....
