Hello,
I am running the square cylinder testing case using the mesh given in the built-in folder of SU2 and try to reproduce the solution of the square cylinder case in the AIAA paper "Stanford University Unstructured (SU2): Open-source Analysis and Design Technology for Turbulent Flows". In order to do that, the free-stream conditions are modified to be as following: MACH_NUMBER= 0.2 FREESTREAM_TEMPERATURE= 273.15 However, I got a St number value quite different from the one given in the paper. St=fL/U=0.083839346 where f = 1/T T = 120 * 0.0015 = 0.18 U = 66.2643 L = 1 Quite confused. Any help is appreciated. Thanks, Paul Attached are the figures where I found that a period has 120 time steps. |

Hi,
My recommendation is to take a look at this paper: https://arc.aiaa.org/doi/abs/10.2514/6.2014-2404 were you can maybe find some extra information. Another thing that you can do is to compare your results with the figure 7 in the article that you cite in case something has changed in the latest releases of SU2. Best, Francisco |

Your reply is just in time. I realized that the SU2 code has been updated which yields a better solution. Thank you so much for your guidance. Best, Paul |
