Selection of Frequency Points

The figure below illustrates the distribution of the frequencies at which the solution is calculated for random vibration studies.

The normalized mapping function is Y = XP where:

P = biasing parameter (power).

Y = uniform scaling between -1 and 1 with the requested number of frequency points.

X = normalized to correspond to -1 for w1 and +1 for wi+1
