Numerical Solution

Solution Methods

In the Outline window, select Solution Methods to open the Solution Methods window. Under Spatial Discretization, change the option under Momentum from First Order Upwind to Second Order Upwind. Under Energy, also change the option to Second Order Upwind.

Monitors

In the Outline window, click Monitors to open the Monitors window. In the Monitors window, select Residuals - Print,Plot and press Edit.... This will open the Residual Monitors window. We want to change the convergence criteria for our solution. Under Equation and to the right of Continuity, change the Absolute Criteria to 1e-6. Repeat for x-velocity, y-velocity, and energy, then press OK.

Solution Initialization

In the Outline window, select Solution Initialization. We need to make an "Initial Guess" to the solution so FLUENT can iterate to find the final solution. In the Solution Initialization window, select Standard Initialization then under Compute from, select Inlet from the drop down box. Check to see that the values that generate match our inputted values, then press Initialize

...

In the Outline window, select Run Calculation. Change the Number of Iterations to 2001000. Double  Double click Calculate to run the calculation. After the calculation is completeiterations have converged, save the project, and you may close the solver.
