Step 5: Solution
Now we will be dealing with the Solution section of FLUENT. Let's first specify the discretization method.
Solution > Solution Methods
Under Spatial Discretization, change Momentum, Turbulent Kinetic Energy, Turbulent Dissipation Rate, Energy to Second Order Upwind discretization method.
Now let's us set the convergence criteria.
Solution > Monitors > Residuals - Print, Plot > Edit...
Enter convergence criteria of 1e6 for continuity, x-velocity, y-velocity, k and epsilon. Click OK to close the window.
At this point, everything is set up properly. We just need to give an initial condition for FLUENT to start the calculation.
Solution > Solution Initialization
Under Compute from, select Inlet and click Initialize.
Now we can solve for a solution.
Solution > Run Calculation
Enter 500 for Number of Iterations and click Calculate. You will see a window message saying Calculating the solution... Wait for FLUENT to finish the calculation.
