When running CFD simulations (Incompressible, Compressible, Convective Heat Transfer, Conjugate Heat Transfer), you should see results after 60 seconds of solver time and halfway through the simulation while the run is ongoing.
You can also see the intermediate results that you have defined in the “Write interval” section of the Simulation Control. You should see them while the simulation is running, but they may have some lag, so if you define the “Write Interval” at 100 for example, and the case is very big, maybe you see the results of iteration 100 when the solver is already at iteration 300.
