Harmonic - Advanced Options

Sets the frequencies at which the response will be evaluated.

No. of points for each frequency Sets the maximum number of frequency points at which the response will be evaluated for each mode. The limit on the total number of solution steps is 15000.
Bandwidth around each frequency A ratio R that sets the range of the solution frequency points around each natural frequency considered in the analysis.

For example, the full range Bi (R =1) for mode i extends from (Fi - Fi-1)/2 to (Fi+1 - Fi)/2 as shown below:

  • A solution frequency point is used at each natural frequency considered in the analysis. If two consecutive modes are too close to each other, the software uses a number of points smaller than No. of points for each frequency.
  • For the first mode, Fi-1 is considered 0. For the last mode, the bandwidth is considered to be symmetrical around the natural frequency.
  • If the upper limit frequency, specified in the Harmonic Options tab, is much larger than the highest natural frequency considered in the analysis, the No. of points for each frequency input is used to define frequency points in that range.
Interpolation

Logarithmic

The solution frequency points are clustered around each natural frequency logarithmically to capture the response accurately at the natural frequency neighborhood. The solution frequency points are shown in pink in the figure above.

Linear

The solution frequency points are distributed uniformly on the bandwidth. The solution frequency points are shown in blue in the figure above.
