Bv98: Error in new sheet for walls and windows corrected.
tsbi5: Converting weather data UI.
Model: Expanded format for weather data: Header: id, latitude and longitude, timezone and height above sea level.
tsbi5: Hour values added for wind direction. tsbi3 format can still be used. Moisture: function to set partial pressure (pb) as a function of the height above sea level.
SimView - HeatBalance graph - choice of type added (Bar, Pie 2D and 3D, Doughnut).
SimDxf - Option maxLine removed.
SimView - Graphs extended with a possibility of fixing the Y-scale from period to period.
tsbi5 - Tsbi5/Tables: shows now parameters from other models.
SimView - Tsbi5/Parameters: Choice of parameters from other models. Log file must be located in the same folder as the actual model (to avoid too long parameter names). Parameter names from other models: model@parametre. In principle there is no limitations in the number of models.
SimView - XSun misc. minor changes and improvements.
The model - Volume of building corrected and CurvePoints removed by CleanDB (moisture).
SimView: ModelList: check layer thickness in constructions > 0.
SimView: Error, if construction layer thickness = 0.
Model: Calculation of net. volume for thermal zones corrected.
SimView: Disable of SimView and XSun during tsbi5/simulation.
SimView: SimLight only active from SimView.
tsbi5: Filename added by copy of sheets to clipboard.
SimView: ModelList: filename and timestamp added, and RoomTemp documented.
tsbi5: Ventilation: correct inlet temperature to time log (before ventilator).
SimView: STEPerror by mixing when air comes from a room (non thermal zone) corrected.
During tsbi5 simulation fixed focus on Simulation Page.
SimView: tsbi5/Options: added layer thickness (maximum layer thickness) as a declaration of maximum thickness for sub-division of material layers (especially used in connection with simulation of moisture in constructions).
tsbi5: Temperature/moisture through constructions saved in the hour-log if moisture simulation is chosen.
SimView: Drag-and-drop implemented to change the order in tsbi5 parameter list.
SimView: CleanModel improved further.
SimView: CleanModel: function which adds missing faces in spaces.
SimView: Added in tsbi5/option Moisture Distribution (only active if the database contains parameters for moisture).
tsbi5: Algorithms for moisture transportation through constructions implemented - is being tested and corrected.
tsbi5: File name, containing '.', gave wrong file name for log files.
SimView: Function for check/edit at FaceSides facing towards a real space added in Edit/CleanModel.
SimView: Delete ThermalZone now saved for Undo.
SimView: Windoor property: disable Override when no type is chosen and show NoType (not Impossible geometry).
SimView: Improved delete (Delete current object).
tsbi5: Insolation through openings added.
tsbi5/XSun solar distribution through windoors and openings corrected to make the heat balance balance.
tsbi5: Distribution through windoors and openings between rooms corrected.
SimDB: Editing Material during editing BuildingElement corrected.
SimView: CleanModel: check and correct faces for Edges not belonging to the face.
Model: Calculation of InnerShell, degenerate of edge with one vertex corrected. (Could make the program break down).
System: New version of Mfc42.dll and Msvcrt.dll in connection with an update of VC++ to Service Pack 4.
tsbi5: Check for number of time steps. New warning: Ask user if the recommended number of time steps is to be used if the given number of time steps is too small.
Model, DisDB: MoistMaterial re-defined to be a sub-type of ConstructionMaterial, meaning if moisture data exists in the database they are added.
SimView, Model, tsbi5: Mixing from spaces outside thermal zones added. (Note: Can not be exported to tsbi3). Mixing via a space, which is analogue to the thermal zone receiving the mixing, can not be simulated (gives an error message before the simulation).
tsbi5: Added error message when constructions are missing at the start of the simulation.
SimView: Copy/Paste in the tree structure now keeps focus.
tsbi5: Export to tsbi3: corrected day profile.
tsbi5: Mixing corrected, unintended reset of volIn and olOut, must happen collectively for all zones before control, as volOut is registered in the thermal zone where air comes from by the thermal zone recieving the air.
SimView: User interface for Ventilation and lighting systems improved.
tsbi5: Corrected error in shadow calculation, could make the program break down.
SimView: Non referred Layers removed by CleanModel. DaylightCtrl added to ModelList.
Model: Ventilation and Lighting UI, choice and change of control corrected in dialog.
Version 188.8.131.52 - 184.108.40.206
SimView have been optimised, including minor corrections, especially in the edit functions.
In tsbi5 shutters and solar shading have been checked and corrected.
SimDxf have been optimised and a control function for saving models as *.dis files holding rooms without a complete description have been implemented. When a model is saved as an *.arc file, 'nodes' are also saved, which was not the case in earlier versions.
The SimDB database module has been extended to support moisture properties for building materials. The changes are not visible when using the existing databases. The moisture model is being developed and will not be available until later.
