Versions

Details on the new features and updates listed here can be found after installing AUSTAL View in the help under „Einführung > Was ist neu“

Version 11

Version 11.0.16

the parameters vq and zq were not transferred at the start of BESMAX program and instead zero values were transferred for the volume flows, so that no thermal rise was taken into account
BESMAX report was not generated for long substance names

Version 11.0.11

in the output of BESMAX, the evaluation of the concentration to the S-value was carried out incorrectly for some substances
spaces are now allowed in the BESMAX path (File > Preferences > BESMIN/BESMAX)
if source parameters are imported via an Excel file, a large number of decimal places may have been displayed in the BESMAX output
when determining the weighted emission center for the odor evaluation grid, the center of the source is now used for extended sources (volume, area, line sources) instead of its origin

Version 11.0.5

austal.exe and taldia.exe replaced – of the two versions of the files austal.exe and taldia.exe provided by the Federal Environment Agency, the slower version (gcc compiler) was included in version 11.0.0
Restriction on exporting and printing output in path or file names with spaces or special characters removed

Version 11.0.0

Please note: Users of the multicore version of AUSTAL must also update: Download (File pk_mpi.3.3.0_AustalView_setup.exe)

New features

Implementation of the new AUSTAL version 3.3.0
Calculation of stack height according to TA Luft Annex 2 Number 14
New BESTAL-Version implemented
New building type polygonal building with inner courtyard („Holes“)
New source parameter rf
When exporting shape files, several layers can now be exported simultaneously
Subdirectories can now also be searched when using the Import tool
Maximum number of monitor points increased from 20 to 199
The maximum length of building and source names has been extended to 16 characters. In addition, the numbering in the standard name of buildings and sources has been increased to 3 digits (e.g. GEB_001 instead of GEB_1).
The maximum permitted number of grid cells has been increased from 300 to 400

Updates and bug fixes

The quality level qs can now be selected up to the value 9 in the control system.
When creating a new project, the last selected UTM or GK zone is set as the default value.
When creating a user-defined grid, the third grid may have been shifted by one mesh, causing AUSTAL to abort.
When outputting a concentration time series, the unit of the y-axis was not displayed correctly.
Incorrect points were deleted when several monitor points were deleted at the same time.
AUSTAL aborts if an outlet temperature tq > 10 is specified, but the source parameters dq and vq are missing. This is now checked in Details and an error message is displayed if necessary.
In simulations with flat terrain, the error message Missing anemometer location was incorrectly displayed.
Variable emissions: in time scenarios with uniform distribution, one hour was sometimes missing.
The Move symbol was sometimes inactive.
Building grid, terrain and time series files were not displayed in the „Save as“ dialogue
The niederschlag.dmna file was not included in the zip backup by default.
Output of the precipitation time series in niederschlag.dmna with two decimal places for more precise scalability to the mean value
Sources with situation-dependent parameters (meteo matrix): Wind classes could only be selected from 1 to 9 instead of in 1m/s steps and the export/import of Excel files was added
When exporting JPG images, the previously selected settings will be used in the selection
Incorrect labelling of the weekdays in the „Emission scenario“ report has been fixed
When selecting a colour palette for the hourly value NO2, the colour palette of the annual value was partially overwritten
When restarting a calculation run in an existing project, the individually selected colour palettes were sometimes reset
Checking for umlauts and symbols in the file path before starting the calculation run
