Add and Remove Input Variables

Input variables can be added to your study manually or imported.

Import Input Variables from HyperMesh or MotionView

Quickly add input variables to your model by importing them from a HyperMesh or MotionView session.

  1. In the Define Models step, click Import Variables.
    The Model Parameters dialog opens.
  2. Select the parameter(s) to add as input variables from the panel on the left.
    Note: For HyperMesh models, you can edit the upper and lower bounds of the input variables during this step.
  3. Click Add.
    The parameters you selected for definition as input variables are appended to the panel on the right.
  4. Click OK (HyperMesh) or Done (MotionView).
The model parameters that were appended to the panel on the right are added to the list of input variables in the Define Input Variables step. Each model parameter is associated with an input variable.

Import Input Variables and Output Responses from Excel Spreadsheets

Quickly add input variables to your model by importing them from an Excel spreadsheet.

Before you begin importing input variables from an Excel spreadsheet, it is import that the data in your spreadsheet is formatted correctly. For more information, refer to the Usability Characteristics section in Spreadsheet Model.
  1. In the Define Models step, click Import Variables.
    The Excel spreadsheet opens.
  2. Select input variables.
    1. In the Excel dialog, click Yes to begin selecting input variables.
      The Excel - HyperStudy Input Selector dialog opens.
    2. In the spreadsheet, select the input variable's value and label cells.
      Note: You can select an input variable's value and label in two consecutive rows or two consecutive columns.
      The selected cells display in the Excel - HyperStudy Input Selector dialog.
    3. Click OK to import the selected input variables.
    4. To continue selecting input variables in other areas of the spreadsheet, repeat steps 2.b and 2.c.
    5. Click Cancel in the Excel - HyperStudy Input Selector dialog to stop selecting input variables.
    Figure 2.


  3. Select output responses.
    1. In the Excel dialog, click Yes to begin selecting output responses.
      The Excel - HyperStudy Input Selector dialog opens.
    2. In the spreadsheet, select the output responses' value and label cells.
      Note: You can select an output responses' value and label in two consecutive rows or two consecutive columns.
      The selected cells display in the Excel - HyperStudy Input Selector dialog.
    3. Click OK to import the selected output responses.
    4. To continue selecting output responses in other areas of the spreadsheet, repeat steps 3.b and 3.c.
    5. Click Cancel in the Excel - HyperStudy Input Selector dialog to stop selecting output responses.
    Figure 3.


The imported input variables are added to the list of input variables in the Define Input Variables step, and the imported output responses are added to the list of output responses in the Define Output Responses step.

Create Input Variables

Manually create input variables in HyperStudy.

  1. In the Define Input Variables step, click Add Input Variable.
    A new input variable is created and added to the list of input variables.
  2. Define the input variable by modifying its corresponding cells in the work area.
    1. Enter a label.
    2. Specify a lower, nominal, and upper bound.
    3. Optional: Change the data type, mode, distribution role, and so on from the Modes and Distributions tabs.
Figure 4.


Tip: Create multiple input variables simultaneously by left-clicking and holding the mouse button on Add Input Variable. In the pop-up, enter the number of input variables to add and press Enter.

Remove Input Variables

Remove input variables from your study.

  1. In the Define Input Variables step, select the input variable to remove.
  2. Click Remove Input Variable.
Figure 6.


Tip: Select multiple input variables to remove by holding Ctrl while left-clicking.
