Summary of steps in the above video:
- Fluent Launcher
- Select double precision
- Select parallel and choose the number of cores, I recommend using as many as you have but note that you need a special HPC license if you choose to use more than 4 cores.
- Models
- Edit viscous
- K-omega
- SST
- Edit viscous
- Cell zone conditions
- Edit Fluid
- Enable Frame Motion
- Specify angular velocity to be -2.22 m/s
- Edit Fluid
Boundary Conditions
We now specify the boundary conditions.

Summary of steps in the above video:
...
- Inlet
- Velocity magnitude: 12m/s
- Inlet-Top
- Component (X,Y,Z): (0,0,-12m/s)
- Blade
- Default, wall
- Periodic 1 and Periodic 2
- Change to Interface
| 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. |

The order in which the interface zones is selected matters because of how the offset is computed. Make the first interface zone periodic 1 and second interface zone periodic 2. Otherwise, you may get the error: Cannot intersect two interfaces. |
