Input Design Variables
An input design variable is a system parameter that influences the system performance in the chosen output response. Typical design variables may be a part's thickness, shape, or material property. Ranges, with lower and upper bounds, are specified and the variable's value will vary within the exploration. The terms input, input design variable, and design variable are used interchangeably.
DOE, Optimization, and Sampling Fit Input Design Variables
The following input design variables are only available for DOE, Optimization, and Sampling Fit explorations.

Design Explorer
Multi-disciplinary design exploration and optimization tools.
- Open the Design Explorer Browser
  The Design Explorer Browser displays a hierarchical view of your design setup and can be used to enable and disable exploration parameters.
- Explorations
  An exploration is a multi-run simulation. Each exploration includes input design variables, and output responses. Explorations may also include goals, consisting of one or more objectives and constraints.
- Input Design Variables
  An input design variable is a system parameter that influences the system performance in the chosen output response. Typical design variables may be a part's thickness, shape, or material property. Ranges, with lower and upper bounds, are specified and the variable's value will vary within the exploration. The terms input, input design variable, and design variable are used interchangeably.
  - DOE, Optimization, and Sampling Fit Input Design Variables
    The following input design variables are only available for DOE, Optimization, and Sampling Fit explorations.
    - Create Gauge Inputs
      Use the Gauge tool to create design variables based on the thickness of selected properties.
    - Create Size Inputs
      Use the Size tool to create size design variables based on the attributes of selected entities.
    - Create Shape Inputs
      Use the Shape tool to create shape design variables based on selected shapes.
    - Create Material Inputs
      Use the Materials tool to create design variables based on material options for selected properties.
    - Create Connector Inputs
      Use the Connectors tool to create design variables based on selected connectors.
    - Create Element Property Inputs
      Use the Properties tool to create design variables based on varying the property assignment for components or elements.
    - Create Parameter Inputs
      Use the Parameters tool to create size design variables by converting existing parameters.
    - Create Configuration Inputs
      Use the Configuration tool to create design variables by selecting two or more subsystem configurations.
    - Replicate Inputs
      Use the Replicate tool to replicate features, such as beads, holes, and dimples, and to generate and replicate doublers or bulkheads.
    - Edit and Preview Design Variables
      Edit design variable properties and preview thickness and shape type inputs.
  - Generative Design Input Design Variables
    The following input design variables are only available for Generative Design explorations.
  - Link/Unlink Design Variables
    Design variables can be linked to one another to ensure that their values remain connected throughout the exploration. This is useful in cases of symmetry or when it is known, for example, that two parts will have the same thickness. In addition, reducing the number of independent variables will reduce the number of runs required for the exploration.
- Output Responses
  An output response is a measurement of system performances, such as mass, volume, displacement, stress, strain, or reaction forces.
- Objectives
  Objectives are metrics to be minimized or maximized in an optimization exploration. Minimizing mass to find a lightweight design is a common example.
- Constraints
  Constraints need to be satisfied for an optimization to be acceptable. Constraints may also be associated with a DOE. While not used in the evaluation of the DOE, constraints can be useful while visualizing DOE results. Limits on displacement or stress are common examples.
- Review and Edit Design Parameters
  Review the explorations, inputs, responses, and goals in your design setup.
- Evaluate
  Use the Evaluate tools to run the exploration and review reports.
