Use the Model Inspector

The inspector separates Behavior from Style: behavior defines model logic and data; style controls appearance and layout.

Behavior

For a simulation variable, common controls include:

• Inputs: connected source variables included in the equation
• Equation: the expression used during simulation
• Unit: the variable's measurement unit
• Graphical Function: an optional lookup relationship
• Use Array / Edit Array: dimensions, elements, and per-element equations
• Documentation: notes stored with the variable
• Expose as Interactive Control: minimum, maximum, and increment for eligible constants

The function browser and optional touch keypad help insert supported expressions. SELF is available where a self-reference is meaningful; a variable cannot reference itself by name.

Stocks use their equation as the initial value. Scalar constant auxiliaries and flows can be exposed as interactive controls; equations that vary over time are not eligible.

Style

Style settings depend on the selection and can include shape, fill, stroke, opacity, label position and size, font, connector appearance, and number format. Use Global Style returns an object to the model theme defaults.

Number formats may inherit the model default or override it per variable. These formats affect displayed values in plots, tables, widgets, and text interpolation; they do not change the simulated numeric value.

Model-level inspector

With no object selected, use:

• Model Settings for time, DT, integration, run duration, Advance Mode, and Diagram Mode
• Data Manager for run history, comparison inclusion, CSV export, deletion, and clearing history
• Model Styles for global primitive and plot appearance
• Mini Map for navigating nodes and connection chains

See Simulation settings and Run history and comparison.
