FE Geometry
FE geometry is topology on top of mesh, meaning CAD and mesh exist as a single entity. The purpose of FE geometry is to add vertices, edges, surfaces, and solids on FE models which have no CAD geometry.

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.
- Output Responses
  An output response is a measurement of system performances, such as mass, volume, displacement, stress, strain, or reaction forces.
  - Create Mass and Volume Responses
    Use the Mass/Volume tool to create mass or volume responses. The resulting response is the mass or volume of the entire model or the mass of an individual property or material.
  - Create Displacement, Rotation, Velocity, and Acceleration Responses
    Use the Disps. tool to create displacement, rotation, velocity, or acceleration responses from selected nodes.
  - Create Stress and Strain Responses
    Use the Stress/Strain tool to create stress and strain responses for selected elements or properties.
  - Create Force Responses
    Use the Force tool to create force responses from 1D elements or constraints.
  - Create Frequency and Buckling Responses
    Use the Frequency/Buckling tool to create modal frequency and buckling responses.
  - Create Connector Responses
    Use the Connector tool to create connector responses. The resulting response is the number of realized connections in the entire model or in selected connectors.
  - Create Fatigue Responses
    Use the fatigue tool to create damage and life responses for selected elements.
  - Create Measure Responses
    Use the Measure tool to create responses for supported measurements.
  - Create Derived Responses
    Use the Derived tool to create responses which are combination of existing responses.
  - Create Generic Response
    Generic responses can be created two ways, by specifying a solver result file containing the desired response or by specifying a session file containing desired response evaluations.
- 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.
Validate
Validate the model built before running solver analysis.
Analyze
Models require loads and boundary conditions in order to represent the various physics and/or physical equivalents to bench and in-use testing.

Create Frequency and Buckling Responses

Use the Frequency/Buckling tool to create modal frequency and buckling responses.

The resulting response is the frequency or buckling eigenvalue of the given mode number.

For frequency responses, a Modal Assurance Criteria (MAC) is created in the background to ensure that the desired mode is evaluated in each run in the exploration. For buckling responses, a (MAC) is not created. The mode shape is not tracked and just the mode number that is specified is reported.

Restriction: Frequency and buckling responses are only supported for the OptiStruct profile.

From the Design Explorer ribbon, click the Frequency/Buckling tool.

Figure 1.
From the guide bar, select Frequency or Buckling.
Click to create the response.
From the microdialog, enter the number of the desired mode.
Make any additional modifications to the created response in the microdialog.

By default, the nominal run result (.h3d file) is used as the reference for mode tracking comparison. Optionally, a reference file of your choice can be selected using the Location field in the microdialog.

Tip: While creating a frequency response, you click in the microdialog to visualize the desired mode with a valid reference file selected. Click to open an animation window where you can select the desired load case and mode and animate the mode shape to assist in mode selection. Selections will be automatically set in the microdialog.
In the microdialog, select Objective or Constraint to simultaneously create one.

Note: You can continue to define the constraint in the microdialog.
