Version 9.1.2 Features and Fixes

Chained slider enhancements — New options and improvements to the chained slider include:

• Ability to enter tenths or hundredths in slider allocations.
• A color-coded sum at the bottom of the chained slider indicates whether allocations equal 100%.
• A new "Distribute" button automatically adjusts sliders proportionately to 100%.
• An option in the Slider dialog to assign unallocated values to another model variable. Read the isee blog for details...

Performance improvements — Simulations now run significantly faster due to overall performance improvements.

New page size option — When setting Interface Preferences, the Page Size dialog now includes an option to use the current printer page settings or to enter a custom width and height in pixels. The "Use Full Size" option allows the user to exactly specify the size of the pages on the Interface instead of the device (screen or printer).

Data import/export directly to CSV files — Data import and export to CSV files no longer uses Microsoft Excel, reducing the time to import or export data in medium or large models.

Command line support for running models — On Windows machines, models can now be run from outside of STELLA or iThink using command line controls. Read the isee blog for details...

Array enhancements — ARRAYIDX and DIMSIZE built-in functions no longer require an array element input. Traditional mathematical notation has been implemented to allow any dimension name in an array equation with "Apply to All" checked to be offset by a positive or negative amount.

Built-in functions — LOOKUP, LOOKUPXY and ARRAYRANK have been added to the list of available built-in functions. Read the isee blog for details...

Interface improvements for negative Stocks — Stocks that can go negative are now marked with an icon in the lower right corner for easy identification. The right-click context menu can also be used to turn on/off the “Non-negative” option for multiple selected Stocks.

New registration options — Upon registration, users now have the option to automatically adjust their Default Settings to "Non-negative" unchecked for Stocks and "Biflow" for Flows.

Animation improvements — The Model Preferences dialog now has a "Disable Discrete Animation" option allowing you to disable Conveyor and Queue discrete animation. Animation for arrayed variables is now based on their sum rather than the front element.

Expanded support for modules — Switches and navigation buttons can now control which modules are running. Graphs, tables, and all other objects support fully-qualified names.

Improved error handling — Invalid diagram operations now provide messages to the user indicating why the operation cannot be performed.

1. When changing an element name in the Array Editor, all equations using the array are now updated to reflect the new name.
2. Fixed a problem whereby disabling the "Apply to All" option in the Array Editor and re-enabling it after edits caused an application failure.
3. Models can now be saved from within a Module if a pad is unpinned.
4. Dragging and dropping a cross-level ghost onto a pad no longer causes the application to fail.
5. Corrected a problem in version 9.1 whereby "Order of execution" equations failed to import to Forio Business Simulations.
6. Equations ordered by Sector now display properly and can be copied and pasted without error.
7. Fixed a problem introduced in version 9.1 that caused the ALT-key to behave improperly.
8. Adding structure in a Module that is connected to an arrayed Stock no longer generates an "applied stream conflict" error message.
9. Copying a variable ghost and pasting it in a module that has an assigned module input with the same name no longer causes the application to fail.
10. The Graphical Function dialog for an arrayed variable now properly displays the x-axis label and column heading when "Apply to All" is unchecked.
11. Corrected an intermittent problem that caused some module outputs to run twice per DT appearing to "race ahead" of other variables when running the model.
12. Circularity is no longer reported when the inflow is used to determine the transit/cook time for an arrested conveyor or oven.
13. "Align to grid" now works properly for buttons, text boxes, and LIDs.
14. Importing data to a queue or conveyor using row orientation now imports correctly.
15. Data import/export now properly handles regional decimal and thousands separators.
16. Fixed a problem opening a nested module containing an array that caused the application to fail.
17. When importing different models into two modules, the application no longer fails if the models contain the same dimension name with different sizes.
18. Links and data files can now be placed in either the "Links" or "Data" directory or in the same directory as the model.
19. Copying models on the same computer now resets import/export data links to point to the moved Data folder.
20. When saving a Module file, the file is no longer overwritten until the save succeeds.
21. Animation for arrayed variables is now based on their sum rather than the front element.
22. The "Allowable List" in the Switch and Graphical Input Device dialogs now displays module names in the correct location.
23. On Windows machines with dual display monitors, dialog windows now appear on the correct display monitor.
24. Corrected a problem with the NPV built-in function that caused the discounting calculation to be off by one DT.
