Solution > Run Calculation 
Enter 500 for Number of Iterations and click Calculate. Note that 500 is the maximum number of iterations we want the solver to carry out. You will see a window message saying Calculating the solution... Wait for FLUENT to finish the calculation. Our solution converges in about 350 - 400  iterations. So the solver will stop the iterations before it reaches the maximum number of iterations specified (500). You should see a residual plot on screen as the computation is being performed. It should look something like this:below. At this point, we have a reasonable solution to the set of algebraic equations generated from the BVP using discretization. 

Save project and exit FLUENT:
