Then, click the Initialize button, . This completes the initialization process.

To run the simulation go to:

Solution > Run Calculation


Execute Calculation

Prior, to running the calculation the maximum number of iterations must be set. To specify the maximum number of iterations click on Run Calculation then set Set the Number of Iterations to 1000. Click Calculate.

Note: There is a bug on FLUENT and you might need to double or triple click the Calculate button to start the simulation.

100, as shown in the image below.

As a safeguard save the project now. Now, click on Calculate two times in order to run the calculation. The residuals for each iteration are printed out as well as plotted in the graphics window as they are calculated and . After running the calculation should converge in about 561 iterations.

Save the solution to a data file after solution is converged by going to:

Main Menu > File > Write > Data...

, you should obtain the following residual plot.

The residuals fall below the specified convergence criterion of 1e-6 in about 48 iterations, as shown below. Actual number of convergence steps may vary slightly.

At this point, save the project once againEnter plateBL.dat for Data File and click OK. Check that the file has been created in your working directory. You can retrieve the current solution from this data file at any time.
