Version 10 makes it even easier to build, share, and learn from STELLA and iThink models.
Side-docked panels allow you to define and edit properties for model entities
while still viewing the diagram. Drag-and-drop
entities from the diagram into equations
to use as variables. Undock the panel to
create a floating window that you can resize
and place anywhere on your screen.
Expanded array capabilities provide more flexibility defining
array equations, creating arrayed graphical
functions, and entering constants across an
array. Create up to ten dimensions for arrayed
entities. Index dimension elements by number
or label. Use the new Array Editor to easily
import or paste element labels from a
spreadsheet or comma/tab-separated list.
|Equation panel with auto-complete functionality
The new Data Manager
allows you to archive and recall simulation
results. Name and save run data from
different scenarios or sensitivity tests to easily
identify and reload results. Simulation data is
stored in a separate SQLite database file and
accessible using standard database tools.
are now embedded in a single model file by
default. For collaborative model building and
creation of reusable templates, use the option
to automatically save modules as separate
Statistical built-in functions
COMBINATIONS, FACTORIAL, INVNORM and PERMUTATIONS
have been added to the list of statistical built-in functions. New stochastic distributions include
BETA, BINOMIAL, GEOMETRIC, GAMMA, LOGISTIC, PARETO, TRIANGULAR, and WEIBULL.
Rich text documentation
Source information and other details about model variables can be
documented in rich text/HTML format using options available in the new Documentation panel.
Improved conveyor leakage
Conveyors now support multiple leakage flows. Use additional
leak zone options to simplify main chain structures that contain cohorts with varying leakage
Conveyors can have multiple leakage flows with varying leak zones
Expanded Find functionality
Use the new Find
palette to locate model entities using string search,
hierarchical views, and filtering capabilities. Drag and
drop variables from the palette directly into variable
equations and input/output devices.
New graphical function options
Edit the input values
(X-axis) of graphical functions to align with your data.
Use the new continuous extrapolation option to linearly
extrapolate values that are beyond the graphed curve.
Industry standard XMILE format
Model files support
the new industry standard (XMILE) for common
interchange of system dynamics models. Use any text or
XML editor to search, edit or document your model.

More powerful modeling engine (STEAM)
STEAM engine does not place limits on the number of
variables, data points and/or time steps. This new more
powerful and flexible engine will provide a solid
foundation for future development and expanded
functionality of iThink and STELLA.
