-Parameter to switch on a y-shift for the recycled inflow turbulence.\\\\
-If '''recycling_yshift''' = .T., the recycled turbulence that is mapped from the recycling plane (see [#recycling_width recycling_width]) to the inflow boundary is shifted in y-direction. This parameter reduces persistent streaks that may occur within the recycling domain. The distance of the y-shift is INT([../d3par#npey npey] / 2), which is in most cases the best distance for effectively reducing streaks in the recycling domain.
-
-Note that '''recycling_yshift''' = .T. requires [#turbulent_inflow turbulent_inflow] = .T..

+Parameter to define a y-shift for the recycled inflow turbulence, given in multiples of PE (may also be negative).\\\\
+E.g. with recycling_yshift = 3  the turbulent fluctuations, obtained at the recycling plane, will be shifted by 3 processors in positive y-direction before being imposed on the inflow. This method can be used to avoid persistent streaks in the longitudinal wind component, that may form in a neutrally stratified boundary layer (detailed information about this method can be found in Munters 2016).

+Note that '''recycling_yshift''' \= 0 requires [#turbulent_inflow turbulent_inflow] = .T..
