Abstract

Efficient and robust anisotropic mesh adaptation is crucial for Computational Fluid Dynamics (CFD) simulations. The CFD Vision 2030 Study highlights the pressing need for this technology, particularly for simulations targeting supercomputers. This work applies a fine-grained speculative approach to anisotropic mesh operations. Our implementation exhibits more than 90% parallel efficiency on a multi-core node. Additionally, we evaluate our method within an adaptive pipeline for a spectrum of publicly available test-cases that includes both analytically derived and error-based fields. For all test-cases, our results are in accordance with published results in the literature. Support for CAD-based data is introduced, and its effectiveness is demonstrated on one of NASA’s High-Lift prediction workshop cases.

在共享内存上为 CFD 应用程序进行各向异性网格适应性调整
高效稳健的各向异性网格适应对于计算流体动力学(CFD)模拟至关重要。CFD 2030 愿景研究》强调了对这项技术的迫切需求,尤其是针对超级计算机的模拟。这项工作将细粒度投机方法应用于各向异性网格操作。我们的实现在多核节点上显示出 90% 以上的并行效率。此外,我们还在自适应流水线中对我们的方法进行了评估,该方法适用于一系列公开的测试案例,其中包括分析得出的场和基于误差的场。对于所有测试案例,我们的结果与文献中公布的结果一致。我们还介绍了对基于 CAD 的数据的支持,并在 NASA 的一个高升力预测研讨会案例中演示了其有效性。
