 In case of the leapfrog scheme a quite restrictive value of '''cfl_factor''' = ''0.1'' is used because for larger values the velocity divergence significantly effects the accuracy of the model results. Possibly larger values may be used with the leapfrog scheme but these are to be determined by appropriate test runs.\\\\
 The default value for the Euler scheme is '''cfl_factor''' = ''0.8.''

+Type of cycle to be used with the multi-grid method.\\\\
+This parameter determines which type of cycle is applied in the multi-grid method used for solving the Poisson equation for perturbation pressure (see [#psolver psolver]). It defines in which way it is switched between the fine and coarse grids. So-called v- and w-cycles are realized (i.e. '''cycle_m'''g may be assigned the values '' 'v' '' or '' 'w' ''). The computational cost of w-cycles is much higher than that of v-cycles, however, w-cycles give a much better convergence.

+Height where the damping layer begins in the [[1d-model]] (in m).\\\\
+This parameter is used to switch on a damping layer for the 1d-model, which is generally needed for the damping of inertia oscillations. Damping is done by gradually increasing the value of the eddy diffusivities about 10% per vertical grid level (starting with the value at the height given by '''damp_level_1d''', or possibly from the next grid pint above), i.e. K,,m,,(k+1) = 1.1 * K,,m,,(k). The values of K,,m,, are limited to 10 m^2^/s at maximum.\\\\
+This parameter only comes into effect if the 1d-model is switched on for the initialization of the 3d-model using [#initializing_actions initializing_actions] = '' 'set_1d-model_profiles'.''

 Average heat flux that is prescribed at the top of the plant canopy.\\\\

 '''Note:''' Instead of using the value prescribed by [#surface_heatflux surface_heatflux], the near surface heat flux is determined from an exponential function that is dependent on the cumulative leaf_area_index (Shaw and Schumann (1992, Boundary Layer Meteorol., '''61''', 47-64)).
