Step 5: Solution

Solution > Solution Methods

We'll use a second-order discretization scheme. Under Spatial Discretization, set Momentum to Second Order Upwind.

...

Solution > Monitors > Residuals 

Set Absolute Criteria for all equations to 1e-6.

Go to Step 6: Post Processing

Go to all FLUENT Learning Modules

...

Click OK.

Solution > Solution Initialization

Use the inlet conditions as our initial guess value. Select inlet under Compute From.

Click Initialize.

We'll iterate the solution until the residual for each equation falls below 1e-6.

Main Menu > File > Write > Case...

This will save your FLUENT settings and the mesh to a "case" file. Name the file plateBL.cas and click OK.

To run the simulation go to:

Solution > Run Calculation

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.

The residuals for each iteration are printed out as well as plotted in the graphics window as they are calculated and 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...

Enter 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.
