Run the icoFoam Solver
Once again, let’s stick with the default physics to start, so click the Run icoFoam button to start the icoFoam utility which solves the incompressible laminar Navier-Stokes equations. The solver will typically take 10-20 minutes to run while the log is displayed in a pop up dialog. The default simulation time settings compute 0.0 to 0.5 seconds with a time step of 0.005 sec and output every 20 steps (0.1 seconds). The simulation is done when the log shows the residuals and related data for “Time = 0.5” followed by the single line with the word “End”. Close the dialog when the solver is done.
