Processing with OpenFOAM OpenFOAM runs with commandsln motorbike case directory ./Allrunwait until it finishes, it may take a couple of ten minutesCheck log.* files in case of any problem
Post-Processing with OpenFOAM run the command in the motorbike directory paraFoamUsing parafoam draw countor plots, and streamlines to analyze your resultsFor tutorial about post-processing you can refer to the post- processing section http://cfd.direct/openfoam/user-guide/tutorials/
