Iterate Until Convergence

...

You'll find that not all residuals have fallen below 1e-6 in 100 iterations. Solve for 200 more iterations. The solution converges in a total of about 210 220 iterations.

We need a larger number of iterations for convergence than in the laminar case since we have a finer mesh and are also solving additional equations from the turbulence model.

Save the solution to a data file:

Main Menu > File > Write > Data...

Enter pipe100x30.dat for Data File and click OK. Check that the file has been created in your working directory.
