source: palm/trunk/SOURCE/inflow_turbulence.f90 @ 4172

Last change on this file since 4172 was 4172, checked in by oliver.maas, 5 years ago
Added optional method for recycling of absolute values of pt and q instead of recycling only the deviations from the mean profile at the recycling plane. With the new method two problems are solved: 1. A horizontally homogeneous temperature and humidity field is achieved, even for non-neutral boundary layers and thus no thermal circulation is triggered. 2. No gravity waves build up at the inflow due to cyclic boundary conditions for pt and q.
