source: palm/trunk/SOURCE/time_integration_spinup.f90 @ 4763

Last change on this file since 4763 was 4750, checked in by suehring, 4 years ago
Indoor-model new: Namelist parameter added to switch-off/on the indoor model during wall/soil spinup; bugfixes concerning indoor model: bugfix in window-wall treatment during spinup - in the urban-surface model the window fraction is set to zero during spinup, so it is done here also; bugfix in wall treatment - inner wall temperature was too low due to wrong weighting of wall/green/window fractions; Revision of 10-cm temperature at vertical walls - assume grid-cell temperature rather than employ MOST; call hourly-based indoor model only once per hour during spinup, not every timestep; add missing dependency in Makefile; urban-surface model: bugfix in openmp directive
