What's New in Version 1.4

  • Improved Chemical Database to include the following updates:
    • Edit the database without having administrator privileges
    • Add Level of Concern (concentration standards) to the modeling runs

      Levels of Concern - BREEZE INCIDENT ANALYST
    • Edit chemicals efficiently and accurately with the improved Chemical Edit window

      Improved Chemical Edit Window - BREEZE INCIDENT ANALYST
  • Implemented numerous bug fixes to the source term calculations and models in Incident Analyst to ensure a smooth modeling experience
  • Added a new Table Objects Tab to speed up scenario setup and editing of sources

    Table Objects Tab - INCIDENT ANALYST

  • Updated ComponentOne to the latest version to improve stability and pave the way for additional improvements in the future
  • Optimized the naming conventions for Chemical IDs manually added by users
  • Added several warning messages, including a warning message:
    • Before automatically changing Surface Roughness when an AFTOX buoyant stack source is added
    • To remind users of the constants used in Antoine Equation (AFTOX) and in Antoine Equation (Reid Equation 3) are corresponding to different pressure and temperature unit
    • If there are decimal points in the humidity value

Bug Fixes

  • Fixed an issue with the shortcut that opens example project
  • Fixed a bug that caused the Help menu to be inaccessible through an existing project
  • Fixed an issue with the calculation of liquid heat capacity for mixtures
  • Fixed an issue with the density of liquid stored at ambient temperature
  • Fixed an issue with the vapor pressure for noncryogenic liquid pool
  • Removed duplicate warning messages for missing chemical property parameters
  • Fixed a bug that displayed the previous summary file when there were no results for the second model run
  • Resolved an issue that caused the pressure display in the summary file to be set as 1 atm for an unconfined pool fire
  • Fixed an issue that caused the spill date to not update after users change the Date and Time of the modeling scenario
  • Fixed an issue with the Save Changes command that prevented saving changes to the Chemical Database
  • Fixed a bug that caused issues when adding more than one new chemical in the Chemical Database
  • Fixed a bug that would cause the user's Chemical Database to sometimes be removed when the software is uninstalled
  • Fixed a bug that would prevent updating chemical names when users edit the Chemical Database
  • Updated the liquid density in pool evaporation in the Chemical Database to use Fixed Value if all components of the mixture have fixed values
  • Fixed an issue with time step calculation in the INPUFF model that caused an incorrect modeling output for the first time step
  • Fixed a bug that prevented calculations for the maximum concentration at given height and time for buoyant plume in the AFTOX model
  • Fixed several bugs in the evaporating pool calculation through Source Term Wizard in the AFTOX model
  • Resolved a bug that displayed the calculated chemical quantity in a pipe for an unlimited supply source in the Source Term Wizard as zero for the AFTOX model
  • Fixed an issue that displayed the wrong vapor pressure when not using a fixed value and caused the calculated emission rate in the Source Term Wizard to be set as zero
  • Fixed the bug that displayed the wrong Richardson number for certain pressurized pipe releases in the Source Term Wizard
  • Fixed an issue that previously prevented the final time and release time from being set as the same in the DEGADIS model for transient releases
  • Corrected the release temperature of transient emission in the default last two lines in the DEGADIS model input file
