source: palm/trunk/SOURCE/inflow_turbulence.f90 @ 4328

Last change on this file since 4328 was 4301, checked in by oliver.maas, 5 years ago
Deleted parameter recycling_yshift. y-shift in case of non-cyclic boundary conditions and turbulent_inflow = .TRUE. is now steered by parameter y_shift, that is also used in case of cyclic boundary conditions.
