    v12 v13  
    77=== Features under development: ===
    88* '''Aerosol chemistry''' (expected February 2018)
     9
    910* '''Biometeorological analysis products''' (expected January 2018)
     11
    1012* '''Indoor climate and energy demand model''' (expected February 2018)
     13
    1114* '''Multi-agent system''' for humans in urban environments (expected May 2018)
     15
    1216* '''RANS mode:''' TKE-epsilon turbulence closure for urban simulations (expected January 2018)
    1317
     
    5256* '''Wind turbine model''' (PALM): A wind turbine model was implemented ([wiki:doc/tec/wtm details]).
    5357
     58
    5459=== Major changes: ===
     60
     61* '''Humidity vs scalar''': Humidity and scalar are now separated.
     62
    5563* '''Multigrid solver''' (PALM): Optimized multi-grid pressure solver is implemented.
     64
     65* '''Non-cycle inflow''': major changes and improvements for non-cyclic turbulent inflow and turbulence recycling.
     66
     67* '''palmrungui''': the mrun GUI was re-designed in python and renamed to palmrungui.
     68
     69* '''Surface layer''': Three different methods are now available to calculate surface-layer scaling variables and fluxes. This basically involves the calculation of the Obukhov length. Three different methods are not available ("old" circular method, Newton interation, and look-up table) (wiki:doc/tec/bc details]).
     70
    5671* '''Surface treatment''':
     72
    5773* '''Topography implementation''': Topography is now considered via flag arrays instead of 2D index arrays. Overhanging structures like bridges are now possible, i.e., the limitation of surface-mounted topography does not exist anymore. A topography filter was implemented that fills holes that consist of only one grid point [wiki:doc/tec/topography#topo details]).
    58 * '''palmrungui''': the mrun GUI was re-designed in python and renamed to palmrungui.
    59 * '''Non-cycle inflow''': major changes and improvements for non-cyclic turbulent inflow and turbulence recycling.
    60 * '''Surface layer''': Three different methods are now available to calculate surface-layer scaling variables and fluxes. This basically involves the calculation of the Obukhov length. Three different methods are not available ("old" circular method, Newton interation, and look-up table) (wiki:doc/tec/bc details]).
    61 * ''Humidity vs scalar''': Humidity and scalar are now separated.

    6981=== Known bugs: ===
     82
     83* Calculation of aerodynamic resistance for building walls needs further adjustment
     84
    7085* LES-LES nesting remains unstable at high grid aspect ratios (so far only tested for a ratio of 10:1)
    71 * Calculation of aerodynamic resistance for building walls needs further adjustment
     86
    7287* Nesting and restarts do not work for chemistry yet
    7388
     
    7792
    7893=== New features: ===
     94
    7995* '''Progress bar''' (PALM): Informative messages during execution and progress bar added
     96
    8097* '''Land surface model''' (PALM): Beta version has been implemented
     98
    8199* '''Radiation model''' (PALM): Simple clear-sky radiation model
    82100
    83101=== Major changes: ===
    84 * '''Parallel NetCDF:''' Peformance optimization for parallel NetCDF on Cray XC systesm
     102
     103* '''Canopy model:''' Canopy model is modularized and controlled by seperate NAMELIST
     104
    85105* '''General changes in code layout:'''
    86106  * ONLY attribute added to all USE statements
    87107  * KIND parameter added to all INTEGER/REAL declarations
    88108  * comment fields for explaining variables added
     109
    89110* '''Lagrangian particle model:''' Completely revised with improved performance and less demand of memory
     111
    90112* '''Large-scale forcing / nudging:''' Some extensions
     113
     114* '''Parallel NetCDF:''' Peformance optimization for parallel NetCDF on Cray XC systems
     115
    91116* '''Performance:''' Code modifications to allow run on 10.000 cores and more
    92 * '''Canopy model:''' Canopy model is modularized and controlled by seperate NAMELIST
