 FFT-method to be used.\\\\
 The fast Fourier transformation (FFT) is used for solving the perturbation pressure equation with a direct method (see [#psolver psolver]) and for calculating power spectra (see [../packages optional software packages]).\\\\
-By default, system-specific, optimized routines from external vendor libraries are used. However, these are available only on certain computers and there are sometimes more or less severe restrictions concerning the number of grid points to be used with them.\\\\
-There are two other PALM internal methods available on every machine (their respective source code is part of the PALM source code):\\\\
+There are two PALM internal methods available on every machine (their respective source code is part of the PALM source code):\\\\
 1.:  The '''Temperton'''-method from Clive Temperton (ECMWF) which is computationally very fast and switched on with '''fft_method''' = '' 'temperton-algorithm'.'' The number of horizontal grid points ([#nx nx]+1, [#ny ny]+1) to be used with this method must be composed of prime factors 2, 3 and 5.\\\\
 2.:  The '''Singleton'''-method which is very slow but has no restrictions concerning the number of grid points to be used with, switched on with '''fft_method''' = '' 'singleton-algorithm'.''\\\\
