Velocity

First, we will look at the velocity vectors of the solution to see if the make intuitive sense. To plot the velocity vectors, go to Results > Graphics and Animations. In the Graphics and Animations Window, select Vectors and click Set Up.... This will bring up the Vectors Menu.

Make sure the settings of the menu match the figure above: namely Vectors of > Velocity, Color by > Velocity, and set the second box as Velocity Magnitude. To see the velocity vectors, press Display.

Pressure Coefficient

Next, we will plot the pressure coefficient along the surface of the airfoil. Click on Results > Plots to open up the Plots Window. Under Plots, select XY Plot, and click Set Up.... In the window that pops up, change the settings Y-Axis Function > Pressure, and change the second box to Pressure Coefficient. Ensure X-Axis Function > Direction Vector. Under Surfaces, select airfoil. See the figure below for help.

When all the settings are correct, press Plot to plot the data to the command window. To save the data to a text file, check the box next to Write to File. You'll notice that the Plot button has been replaced by a button marked Write..., click it. Change the file type to All Files and save the file name as Pressure_Coefficient.txt

Coefficients of Lift and Drag

To find the Coefficients of Lift and Drag, click Results > Resports to bring up the Reports Window. In the Reports Window, select Forces and click Set Up.... This will bring up the Force Reports menu

Under the default parameters shown above, drag across the airfoil will be displayed. Click Print to print the drag coefficient to the command window. To print the lift coefficient, in the Force Reports window change the Direction Vector such that X > 1 and Y > 1
