Post Processing

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:

Outlet Velocity Profile

From the menu, insert > location > line. Name it "Outlet"

In the Details of Outlet panel, enter the coordinates of the top and bottom vertex at the outlet. Change the number of samples to 50. Click on Apply to create a line at the outlet.

Insert a chart from the menu: insert > chart. Name the chart "Outlet Velocity Profile". Change the title to "Velocity Profile" in the General tab. In the Data Series tab, rename Series 1 to FLUENT and select Outlet for location. Select Velocity as the variable in the X Axis tab and select Y as the variable in the Y Axis tab. Click on Apply to generate the chart.

The velocity profile at the outlet is shown below:

We would like to compare the FLUENT result to the Blasius boundary layer solution. Download the Blasius solution here. Return to the Data Series tab and insert another data set. Rename it Blasius. Instead of specifying the location of the data, select the Blasius solution file you have downloaded.
