Windowing Type
A typical modal transient run is a time based analysis. For optimizing the E-Line for systematic or a non-systematic optimization problem in the frequency domain, we need to convert the time domain data in the input deck to the frequency domain.
Based on the type of windowing option in time to frequency conversion, the default parameters automatically populate.
Hanning
This window function has a sinusoidal shape and results in wide peak but low side lobes.
Touches zero at both ends eliminating all discontinuity.
This is satisfactory in 95 percent of cases.
Uniform
Is also called No Window or Rectangular Window.
The signal is convolved with a rectangular-shaped window of uniform height, by the nature of taking a snapshot in time of the input signal and working with a discrete signal. This convolution has a sine function characteristic spectrum.
Number of Blocks
Perform a block based FFT where the signal is processed by breaking it into given no of blocks and suitable windowing technique is used to reduce the effects of the leakage.
Overlap (%)
Overlap percentage is also a measure to reduce the truncation effects.
The overlapping windows with suitable windowing type like hanning or uniform helps in providing smooth transition from one block to the next.
