Numerical Solution

Here, we tell FLUENT which solution method to use, how many iterations to perform, how to initialize to solution and what to visualize during the calculation. Finally, we run the calculation.

Info

This module is from our free online simulations course at edX.org (sign up here). The edX interface provides a better user experience and the content has been updated since it was first recorded, so we recommend that you go through the module there rather than here. Also, you will be able to see answers to the questions embedded in the module there.

Note
titleNote

In the above video we set the residuals to be very small, at 1e-6. This effectively ensured that the calculation did not stop before before the 1500 iterations specified. A solution is deemed to have converged (and the calculation ends) when ALL residuals fall below the limit set. Although I forgot to input 1e-6 for k and omega, the outcome is the same because the x-velocity, y-velocity and z-velocity residuals had not reached 1e-6.
