We will use CFD-Post as the primary post processing GUI. Steps for post processing in FLUENT can be found here. |
Step 6. Results
Double click on Results from the Workbench Window to launch CFD-Post.
Velocity Vectors
Click on the z-axis, 
to view the XY plane. Click on the vector icon to insert a vector plot. Name it Velocity Vector.
A panel named "Details of Velocity Vector" will appear right below the outline window. Set the Locations to symmetry 1. Click on Apply to display the velocity vectors.
The velocity vectors will be displayed in the view window.
You can use the wheel button of the mouse to zoom into the region that closely surrounds the plate, to get a better view of the boundary layer velocities:

Note: In the below video (Plot Pressure Contours), please note that the cursor disappears accidentally at the 44 second mark and returns at the 3 minute mark. At 1 minute 17 seconds, "here" refers to the bottom-middle of the region near the plate. It is later drawn at the 1 minute 28 second mark. At 2 minute 40 seconds, "here" refers to the left most face, known as the inlet face, of the region.
