Variables

Variables are the backbone of workflow connectivity. You can:

• Create and organize variables for each component.
• Define properties such as type, units, and constraints.
• Establish links between variables to automate data flow.
• Manage arrays and reference variables for advanced modeling.

Core Capabilities

1. Variable Creation

   • Add input and output variables directly from the Component Tree or the Variables panel.
   • Assign meaningful names and descriptions for clarity.

2. Property Management

   • Configure essential attributes:
     • Type: Numeric, string, boolean, file, geometry, or reference.
     • Units: Apply consistent measurement systems.
     • Bounds: Set upper and lower limits for numeric variables.
     • Enumerations: Define allowed values and aliases for user-friendly input.

3. Linking and Data Flow

   • Link input variables to outputs from other components.
   • Use linking to enforce dependencies and reduce manual updates.
   • Visual indicators show linked status in the interface.

4. Array Handling

   • Create arrays of supported types (doubles, integers, references).
   • Dynamically resize arrays to accommodate variable-length data sets.

5. Reference Variables

   • Use in driver components for optimization and trade studies.
   • Define equations referencing other variables for calculated values.

Interface Highlights

• Variables Panel: Displays all variables for the selected component with filtering and sorting options.
• Property Editor: Provides a detailed view for editing attributes, including advanced settings like binary flags and file extensions.
• Icons and Indicators:
  • Input, output, and linked variables have distinct icons.
  • Warnings for missing values or constraint violations.

Advanced Features

• Batch Editing: Modify multiple variables simultaneously.
• Import/Export: Load variable definitions from external files or export for reuse.
• Validation Tools: Check for missing links, invalid bounds, or type mismatches.
