Ansys 3D Fluent: How to Graph Pressure Over Time on the Inside Surface of a Wind Tunnel

         I am attempting to simulate the pressure exerted by the air moving through a wind tunnel on the internal surface of the wind tunnel, but cannot figure out how to record or graph the values of pressure with respect to time on a chart in CFD-Post. I also am unsure on the process of changing the graph from the time domain to the frequency domain using Fast Fourier Transform within the program. I have been able to create pressure contour graphs within CFD-Post, but have been unable to convert that data onto a graph with the pressure on the y-axis and time on the x-axis. Any help would be appreciated.

      It'll be possible (somehow) but will require you to use all the saved data sets to create the graph.  We typically monitor the pressure on a point/surface/line/etc during the run to get this sort of information.
