Level II Software Update

Version 3.00 - September 2005


Since the Version 2.17 (September 1999) release:

Simulation ID
  • There is now an input box for additional notes which is then inputted directly into the print simulation section and will appear on the final printout.
    Chemical Properties
  • There is a change to the half-life checkboxes. When the half-life checkbox is ticked so that the half-life is considered to be negligible and then the user enters a new half-life into the input box the check box is unchecked and the new value is stored.
  • The Henry’s Law Constant display has been removed from this form and is now only viewable in the results form. This has no affect the user’s results.
    Environmental Properties
  • Addition of an environmental database. This database functions in the same manner that the chemical database functions.
  • A water volume of 0 m3 is now allowed. When this value is entered it will automatically change the volumes for sediment, fish, and suspended particles to zero m3.
    Emissions
  • There are no changes to this section.
    Chemical Parameters
  • Same information is being displayed, it is organized differently.
    Environmental Parameters
  • Emissions and Inflows are now displayed on the Results form.
    Results
  • Unit conversions are displayed as options as opposed to buttons.
  • Modified grids to match format of Level III.
  • Concentration now displayed in alternate units.
    Diagram
  • The same information is being displayed, but appearance has been updated.
    Charts
  • Addition of charts to display Concentration (g/m3), Amount (kg), and Relative Amount (%)
    Error Checking
  • Error checking for single corrected.
    Calculations
  • Fixed print out of calculations, it now correctly prints same information that is displayed
    Print
  • The option for printing the date and time when printing Tables has been corrected so that it works.
  • Note: All corrections to units and calculations in above sections have carried over to the printout.
    Save to File
  • Now saves file as .csv format instead of a .txt format.
    About
  • The New Features Button.
