OpenFOAM data for a circular cylinder wake flow (Re=300)

The current dataset contains numerical results from openfoam simulation of a cylinder wake at reynolds number Re=300. The geometry has been constructed using blockMesh followed by snappyHexMesh tools : the 3D domain is a [0:20]x[-10:10]x[0:3.14] box crossed by a Z axis cylinder centered at Ccyl=(5,0) with a radius Rcyl=0.5. As for the simulation, the pimpleFoam solver of openfoam 21.12 has been used, followed with parafoam for post treatment visualization, and ITHACA-FV for POD The code has been run on a cluster with almost 28 CPUs with commands like : RUNNING decomposePar -decomposeParDict system/decomposeParDict -force mpirun -n 28 pimpleFoam -parallel mpirun -n 28 redistributePar -parallel -reconstruct -overwrite POST treatment In current directory, Iso Q generation for visualization : postProcess -func Q -time "500:600" In POD-* directory, POD using ITHACA-FV library and ANR code RedLUM. POD is performed on 500:1000 (train set) using the snapshot method. Temporal modes are also evaluated on 1000:1100 (test set) by snapshot projection.
