Organization of axisymmetric Fourier harmonic analysis results
In the Post Processing Navigator, the results for a axisymmetric Fourier harmonics analysis include an iteration layer based on harmonic index.
Fourier axisymmetric display options
To render Fourier axisymmetric results, use the Axi-Symmetric Display Options dialog box, which you access from the Result dialog box. You can:
Show the results at a particular revolve angle on the original 2D section. For example, you could show the results calculated at an angle of 135 degrees.
Envelope around all or part of the circumference of the original 2D section, looking for values, such as maximum, minimum, and average. For example, you could find the peak radial displacement that occurs between 135 and 270 degrees.
