STREAmS-2.1: Supersonic turbulent accelerated Navier-Stokes solver version 2.1

Year: 2025

Type: article

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.
