Perform Studies
A study is a self-contained project in which models, variables, output responses, and approaches are defined.
Setup the Study
Before you can create approaches you must first setup your Study by defining input variables and output responses.
Define Definition
Define the models, input variables, and output responses to be used in the study.
Define Input Variables
An input variable is a system parameter that influences the system performance in the chosen output response. It is an object that is varied by the study based on certain rules.
Deactivate Input Variables
By default, all input variables imported or manually added to your study are made active. Make an input variable inactive so that it is no longer an independent variable.

Perform Studies
A study is a self-contained project in which models, variables, output responses, and approaches are defined.
- Setup the Study
  Before you can create approaches you must first setup your Study by defining input variables and output responses.
  - Edit Files
    Use the Editor to create and edit template files, parameterize ASCII files, create variables or shape templates, recognize and edit Templex statements in files, execute parameterized files, and perform advanced editing.
  - Define Definition
    Define the models, input variables, and output responses to be used in the study.
    - Define Models
      A model is part of a study. It is the model of the system that is subjected to a study.
    - Define Input Variables
      An input variable is a system parameter that influences the system performance in the chosen output response. It is an object that is varied by the study based on certain rules.
      - Add and Remove Input Variables
        Input variables can be added to your study manually or imported.
      - Deactivate Input Variables
        By default, all input variables imported or manually added to your study are made active. Make an input variable inactive so that it is no longer an independent variable.
      - Link Input Variables
        Reduce the number of independent variables and/or of different models in multi-model studies in order to have synchronized design updates between models by linking input variables to each other.
      - Create Input Variable Constraints
        Define an inequality constraint condition that is a function of only the input variables.
      - Input Variable Properties
        In the Define Input Variables step, various input variable properties can be modified from the Bounds, Modes, and Distributions tabs.
    - Test Models
      Write input files, execute analysis, and extract output responses for models defined in the study Setup.
    - Define Output Responses
      An output response is a measurement of system performances, such as weight, volume, displacement, stress, strain, reaction forces, and frequency.
- Setup the Approaches
  Once the study Setup is complete, an unlimited combination of approaches can be added to a study. A study approach is a specific set of steps taken to study the mathematical model of a design.
Learn the Approaches
Each approach in HyperStudy serves a different purpose in the design study.
Customize HyperStudy

Frequently Asked Questions
This section provides quick responses to typical and frequently asked questions regarding HyperStudy.

Deactivate Input Variables

By default, all input variables imported or manually added to your study are made active. Make an input variable inactive so that it is no longer an independent variable.

Reducing the number of independent variables can reduce the number of runs required in an Optimization or DOE approach.

In the Define Models step, Active column, clear the input variable's corresponding checkbox.
