**7. ANSYS fluent setup: a quick glance**

This section will examine how the simulation was run in ANSYS. The various subsections will look at different steps in the execution order. Fluent will need a lot of data and setup before running the simulation and getting results. Before running the simulation, all properties, boundary conditions, and a few other parameters must be defined. One can note that there is symmetry in a wind turbine blade. It repeats every 120 degrees, normal to the rotational axis. We can save much time by simulating only this 120-degree portion and then repeating the graphical "Instances" every 120 degrees. This will be seen in the final results subsection.

Any **ANSYS Fluent** project will go through the same five steps:

*Results in CFD-Post. Notice the 3-bladed turbine generated from a 1/3rd portion.*
