- lambdaWavelength cut off (set to about twice the interfacial width)
C++ Type:double
Unit:(no unit assumed)
Controllable:No
Description:Wavelength cut off (set to about twice the interfacial width)
FourierNoise
Generate noise from a fourier series
This object generates a Fourier series with random coefficients , , and an amplitude factor (scale). The series can be cut off at a given length scale (lambda) resulting in a low pass filtered white noise. For efficiency lambda should be chosen larger than the smallest mesh element size.
Alternatively the series can be constructed with an entirely random set of series terms by specifying the number of terms num_terms resulting in a non-periodic noise.
Input Parameters
- num_termsNumber of random fourier series terms (this will result in non-periodic noise). Omit this parameter to obtain a periodic noise distribution.
C++ Type:unsigned int
Unit:(no unit assumed)
Controllable:No
Description:Number of random fourier series terms (this will result in non-periodic noise). Omit this parameter to obtain a periodic noise distribution.
