Abstract

We present STREAmS-2.1, an updated version of the flow solver STREAmS [1], lastly updated in Bernardini et al. Comput. Phys. Commun. 285 (2023) 108644. STREAmS-2.1 merges the features of the curvilinear solver FLEW [2] which is able to simulate three canonical cases, namely the circular arc channel, the curved boundary layer and the airfoil case. Moreover, three new backends are included, i.e., OpenMP (for CPUs), HIP (for AMD GPUs) and OpenMP-offload (tested on Intel GPUs but potentially portable). Finally, in situ visualization layer based on Catalyst2 technology is integrated into the solver to reduce the visualization effort, especially for huge computational grids.

STREAmS-2.1：超音速湍流加速Navier-Stokes求解器版本2.1

我们推出了STREAmS-2.1，这是流求解器STREAmS[1]的更新版本，最后在Bernardini等人的版本中更新。第一版。理论物理。common . 285(2023) 108644。STREAmS-2.1融合了曲线求解器flight[2]的特点，能够模拟三种典型情况，即圆弧通道、弯曲边界层和翼型情况。此外，还包括三个新的后端，即OpenMP（用于cpu）， HIP（用于AMD gpu）和OpenMP-offload（在英特尔gpu上测试，但可能可移植）。最后，将基于Catalyst2技术的现场可视化层集成到求解器中，以减少可视化工作量，特别是对于巨大的计算网格。

期刊介绍： The focus of CPC is on contemporary computational methods and techniques and their implementation, the effectiveness of which will normally be evidenced by the author(s) within the context of a substantive problem in physics. Within this setting CPC publishes two types of paper. Computer Programs in Physics (CPiP) These papers describe significant computer programs to be archived in the CPC Program Library which is held in the Mendeley Data repository. The submitted software must be covered by an approved open source licence. Papers and associated computer programs that address a problem of contemporary interest in physics that cannot be solved by current software are particularly encouraged. Computational Physics Papers (CP) These are research papers in, but are not limited to, the following themes across computational physics and related disciplines. mathematical and numerical methods and algorithms; computational models including those associated with the design, control and analysis of experiments; and algebraic computation. Each will normally include software implementation and performance details. The software implementation should, ideally, be available via GitHub, Zenodo or an institutional repository.In addition, research papers on the impact of advanced computer architecture and special purpose computers on computing in the physical sciences and software topics related to, and of importance in, the physical sciences may be considered.
