We will now do some post-processing of the icoFoam/cavitycase, with the purpose of learning the basics of Paraview. It looks slightly different if you use the OpenFOAM reader that comes with Paraview.

Hello, I am using paraview to visualise data from simulations done in OpenFOAM, a CFD toolbox, I am looking to extract the number of cells inside my mesh to I can add it to my python script created by trace tool. otaolafr (franco otaola) May 3, 2021, 7:03pm 1. Courant Number mean: 0.222158 max: 0.852134 smoothSolver: Solving for Ux, Initial residual 2.32737e-07, Final residual 2. 55 commonly-used Courant numbers may not be su ciently small to accurately simulate 56 gravity waves, indicating that many past results might not have converged.
