v12 v13 7 7 === Features under development: === 8 8 * '''Aerosol chemistry''' (expected February 2018) 9 9 10 * '''Biometeorological analysis products''' (expected January 2018) 11 10 12 * '''Indoor climate and energy demand model''' (expected February 2018) 13 11 14 * '''Multi-agent system''' for humans in urban environments (expected May 2018) 15 12 16 * '''RANS mode:''' TKE-epsilon turbulence closure for urban simulations (expected January 2018) 13 17 … … 52 56 * '''Wind turbine model''' (PALM): A wind turbine model was implemented ([wiki:doc/tec/wtm details]). 53 57 58 54 59 === Major changes: === 60 61 * '''Humidity vs scalar''': Humidity and scalar are now separated. 62 55 63 * '''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 56 71 * '''Surface treatment''': 72 57 73 * '''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.62 74 63 75 … … 68 80 69 81 === Known bugs: === 82 83 * Calculation of aerodynamic resistance for building walls needs further adjustment 84 70 85 * 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 72 87 * Nesting and restarts do not work for chemistry yet 73 88 … … 77 92 78 93 === New features: === 94 79 95 * '''Progress bar''' (PALM): Informative messages during execution and progress bar added 96 80 97 * '''Land surface model''' (PALM): Beta version has been implemented 98 81 99 * '''Radiation model''' (PALM): Simple clear-sky radiation model 82 100 83 101 === 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 85 105 * '''General changes in code layout:''' 86 106 * ONLY attribute added to all USE statements 87 107 * KIND parameter added to all INTEGER/REAL declarations 88 108 * comment fields for explaining variables added 109 89 110 * '''Lagrangian particle model:''' Completely revised with improved performance and less demand of memory 111 90 112 * '''Large-scale forcing / nudging:''' Some extensions 113 114 * '''Parallel NetCDF:''' Peformance optimization for parallel NetCDF on Cray XC systems 115 91 116 * '''Performance:''' Code modifications to allow run on 10.000 cores and more 92 * '''Canopy model:''' Canopy model is modularized and controlled by seperate NAMELIST 117 93 118 94 119 === Bugs fixed: ===
