MIND: Linux Version needs Qt 5.15.2 installed, deb-package is following later

v1.0.5 - Bugfix release

In this release the focus was to fix some bugs

• lots of bug-fixes, see detailed list
• view factor request only upon internal long-wave calculation
• project notes were not initialized correctly

v1.0.4 - Major improvements and new features

The release contains several bug-fixes and improvements such as:

• Several bugfixes, see detailed list
• Major improved IFC import, see detailed list
• Coloring improvements of navigation tree
• Standard constructions can now be set in smart-clipping dialog
• Auto-checking of surface orientation in rooms
• major UI improvements in property widgets
• Inside and outside-view of boundary conditions addded
• Constuction-view completely redesigned

v1.0.3 - Energiewende Bauen Release

Energiewende Bauen Release

Some new features including:

• Enhanced boundary conditions view with option to check outer boundary conditions
• Auto-save function: the project will be saved automatically in a custom time interval (default 10 min). In case of a crash, a recovery option is available
• much clearer naming of dialogs and widgets in german translation

Moreover, lots of bugfixes have been implemented:

• bugfix clipping algorithm
• bugfix rubberband selection
• performance improvement in interlinked table widget

v1.0.2 - building training session release

building training session release

In preparation for the upcoming workshop for building simulation, we have done even more bug fixes and lots of convenience enhancements, including:

• enhanced database dialogs, with filter function and legend
• bugfix smart clipping algorithm
• more robust face normal calculation
• long wave radiation model inside rooms: inner wall surfaces can exchange long wave radiation now

v1.0.1 - bugfixes and translation improvements

Several bugfixes and additional translations after our major Release 1.0

v1.0.0 - First major release

Version 1.0.0

We have put a lot of work in the last months - now it is done - SIM-VICUS version 1.0.0 is available. The most important new features are...

• Smart Clipping Algorithm: Rooms with different geometries can be automatically clipped and thermally connected. This makes the creation of complex building models much easier.
  IFC Import: IFC files can be imported directly into SIM-VICUS, which significantly shortens manual processing.
• geoJSON import and export: For networks, geoJSON files can be imported and exported with corresponding attributes (pipe diameter, connection power).
• Live result display: Simulation results can be displayed in color directly in SIM-VICUS. The buildings/networks are colored live and time-dependent by interpolated colormaps.
• Shading calculation: The shading calculation has been revised and in addition to the classic ray tracing there is now the possibility to pre-calculate shading factors by means of area clipping. This makes the pre-calculation even faster!
• New design: All building and mesh properties are now even more clearly accessible.
• Numerous other bug fixes and minor improvements

v0.9.1-beta Bugfix Release

Several bugfixes have been done.

• crash in surface connection table widget fixed
• copy structure fixed for buildings
• corrected german translation

v0.9.0-beta - BauSIM Release

Lots of new features and bugfixes have been implemented until the last minute of BauSIM 2022, preparing SIM-VICUS for the according Workshop. Main changes include:

• new structuring of add / edit geometry and parametrization modes, including new icons
• revised database dialogs, including many plots for enhanced usability
• new feature: thermo-hydraulic networks can now created, edited and parametrized, making it usable for everyone
• added demo examples for buildings and networks: you find them on the welcoming screen -> demo casees
• many validation cases for NANDRAD solvers have been conducted within the SimQuality test suite (see www.simquality.de)
• updated the entire german translation, all dialogs should now be usable in both english and german

We hope you enjoy the new version and that our nightly sessions have lead to a successfull release!

Note: Linux release requires installed qt5 libraries and recent gcc libs (was built on Ubuntu 22.04 LTS). Debian deb packages follows in release PPA.

v0.8.0-beta - Towards real-life projects

Since the last release before Christmas we have done quite some changes to the software. While the NANDRAD solver itself is already quite mature, we put a lot of effort into the user interface, specifically geometric editing. While the IFC-Import plugin is getting closer to the first release, we need more modeling capabilities in the user interface. In the process, we re-arranged the various add and edit functions and created a vertical toolbar as separator between property windows and modeling area:

Now translation, rotation and scaling works reliably, even for arbitrary oriented local coordinate systems. We also made the transformation edit operations a two-stage process: first, a preview of the resulting transformation is shown, and you may then apply or reject these changes.

The german translation is included, but will be extended in the next days (until release 0.8.1), so that most of the UI are now fully available in German.

There has been some work towards hydraulic network modeling as well, yet, this part of the software is still considered highly alpha stage.
