+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 optional software packages, [[4.2]]).\\\\
+By default, system-specific, optimized routines from external vendor libraries are used. However, these are available only on certain computers and there are more or less severe restrictions concerning the number of gridpoints 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):\\\\
+1.:  The '''Temperton'''-method from Clive Temperton (ECWMF) which is computationally very fast and switched on with '''fft_method''' = '' 'temperton-algorithm'.'' The number of horizontal gridpoints ([#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 gridpoints to be used with, switched on with '''fft_method''' = '' 'singleton-algorithm'.''

+Time to be simulated for the [[1d-model]] (in s).\\\\
+The default value corresponds to a simulated time of 10 days. Usually, after such a period the inertia oscillations have completely decayed and the solution of the 1d-model can be regarded as stationary (see [#damp_level_1d damp_level_1d]). This parameter is only in effect if the 1d-model is switched on for the initialization of the 3d-model with [#initializing_actions initializing_actions] = '' 'set_1d-model_profiles'.''
