A holistic microclimate model

<WRAP left round important 60%> To use an existing license, this release requires a one-time automatic license key update for licensed users which needs administrative interaction. In a running project or class, it is recommended to allocate a free time slot for this process. Further information about the license conversion can be found [[http://www.envi-met.net/hg2e/documents/2019_How_to_convert_Licenses.pdf|here]] </WRAP> <WRAP left round box 60%> <fs xx-large>ENVI-met updates for version 4.4.5 (Summer 20)</fs> <fs x-large>Major updates</fs> == ENVI-core == * New calculation method for pressure solver -> Increased stability significantly, reduced simulation crashes (especially instabilites in the Air Temperature, Humidity or CO2 fields). Old pressure solver can still be enabled in ENVI-guide. * Improved NetCDF outputs: Missing Values, Valid Ranges, GridMapping were added to each variable, dimension variables are tagges as axis variables, 2d fields of UTM coordinates including rotation are added * Added a check for necessary NetCDF Microsoft libraries during initialisation of simulation == Other Apps == * BIO-met: Enabled the possibility to write NetCDF outputs * SPACES: Added the option to allow simple changes in vertical gridding even when using Detailed Mode (3D) and to delete existing ghost cells of model areas by reconverting to 2.5D * ForcingManager: ForcingManager can be started using parameter values to create Forcing File (grasshopper plugin support) * MONDE: Additional export options for INX conversion (vertical gridding etc.) <fs x-large>Bugfixes/ Changes</fs> == ENVI-core == * Bugfix DEM: Corrected waterspray units [ug/s] as input * Bugfix Radiation: Corrected shortwave radiation received on roofs * Bugfix: Wind field initialization == Other Apps == * BIO-met: Old singlecore Biomet Version 1.5 is not included anymore, users with an old Biomet license need to download it separately * SPACES: Bugfix: Fixed 3d view issue caused by trees * MONDE: Fixed OpenTopography import * MONDE: Builings in model areas featuring DEM don't have steps in the the roof anymore. Average height of DEM on built-up area is used to "elevate" buildings ---- <fs xx-large>ENVI-met updates for version 4.4.4 (Winter 19/20)</fs> <fs x-large>Major updates</fs> == ENVI-met == * Added Building Performance Simulation Forcing Outputs -> Text file outputs of previously specified Building Numbers that can be used as input for BPS models such as TRNSYS * Added the possibility to force precipitation using Full Forcing * Added a time estimation for the simulation finish as well as a progress bar to visualize the simulation progress * Added the ability of writing NetCDF output files directly through the simulation instead of converting them in postprocessing. NetCDF output files are produced for every hour but hold all data within a single file (no different files are created for atmosphere, buildings, surface, vegetation etc.). Building data needed to be splitted into fields holding either X, Y, or Z data. If simulation crashes during file writing when NetCDF outputs are activated, most likely there is a Microsoft Component missing: Please install Microsoft Visual C++ 2010 SP1 Redistributable Package (found here: https://www.microsoft.com/en-hk/download/confirmation.aspx?id=13523). * Added enhanced error messages to simplify the process of understanding and fixing issues * Added an additional EXE (envimet4_DEBUG.exe) to send automatically generated error messages to an ENVI-met bug report mail address (forum posts may refer to such a bug report mail) == Other Apps == * BIOmet: BIOmet 2.0 is parallelized and thus much faster (but needs the new license type delivered with beginning of version 4.4.3 and an internet connection for server communication) * SPACES: Added the option to allow simple changes in vertical gridding even when using Detailed Mode (3D) and to delete existing ghost cells of model areas by reconverting to 2.5D * ForcingManager: Added the possibility to force precipitation with FOX-files: when FOX-files are created from CSV the precipitation column must exist now (even if empty -> filled with 0) * ForcingManager: Added the possibility to create FOX files from TRY files in addition to EPW files * LEONARDO: Added the support of the temperature unit Fahrenheit <fs x-large>Bugfixes/ Changes</fs> == ENVI-met == * Bugfix DEM: Exposition, Inclination now calculated according to commonly used algorithms of GIS programs -> radiation values should be more accurate now due to correction of the lambert factor * Bugfix Radiation: Direct radiation values were indicated as horizontal but were not; now there are two output fields for direct radiation: on a horizontal surface and on a surface adapted to be perpendicular to the sun by lambert factor * Bugfix: Avoided the crash at simulation check with IVS and receptors * Bugfix: Corrected vertical gridding for Telescoping (old model areas could be gridded differently but more precisely with the new version) == Other Apps == * ForcingManager: Added a correction of wind speed if CSV or EPW/TRY files contain wind speeds of 0.1 m/s or below for a timestep -> the values are then corrected to 0.1 m/s to avoid simulation crashes * ForcingManager: Added the option to refresh the graphs in the data view of the forcing file (e.g. if zoomed in before) * FocingManager: Bugfix: Wind calculation for wind speed in 2500 m corrected (values were too high) * SPACES: Bugfix: Corrected vertical gridding for Telescoping (old model areas could be gridded differently but more precisely with the new version) * SPACES: Bugfix: No ghost cells if telescoping height starts below highest building (also due to the new vertical gridding) * SPACES: Bugfix: SingleWalls checkbox about follow terrain now works correctly * SPACES: Bugfix: Model area bounding box is now sized correctly * DBManager: Bugfix: Deleting Items sometimes caused an exception * DBManager: Bugfix: TrafficTools now allow FloatingPoint values * ENVIGuide: Added several features to the Output Settings in the Advanced Section by the options of writing NetCDF outputs additional to the ENVI-met output files, the option of Including the Nesting grids in output files, and the possibility to write Building Performance Simulation Forcing Outputs * ENVIGuide: Added handling of Threading in expert settings (allows the simulation window to be responsive all the time if activated) * ENVIGuide: Moved the option Adjust Minimum Flowsteps from expert settings to FullForcing settings and added the Force Precipitation option to the page * ENVIGuide: Bugfix: Changed that the short name will now be used as default SIMX name suggestion and the output folder now shows correct path where output will be stored * ENVIGuide: Removed specific information buttons (the information is always visible now) ---- <fs xx-large>ENVI-met updates for version 4.4.3</fs> <fs x-large>Major updates</fs> * ENVI-met: Added a new license system: **PCs need to be connected to the internet at start of a simulation**.
