Browsers
Browsers provide a structured view of model data, which you can use to review, modify, create, and manage the contents of a model. In addition to visualization, browsers offer features like search, filtering, and sorting, which enhance your ability to navigate and interact with the model data.
Sketching
Create and edit 2D parametric sketch geometry.
Topology
Create, edit, and cleanup geometry.
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.
Meshing and Elements
Explore the different types of mesh you can create in HyperMesh and create and edit 0D, 1D, 2D, and 3D elements.

Composites
HyperMesh composites modeling.
Connectors
Create connections between parts of your model.
Morph
Rapidly change the shape of the FE mesh without severely sacrificing the mesh quality.
Skeleton Modeling
Create a reduced ordered model to facilitate optimization at the concept phase.
Design Space
Workflow to support topology optimization model build and setup.
Optimization
Setup an Optimization in HyperMesh.
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 Responses
    Use the Frequency tool to create modal frequency responses. The resulting response is the frequency of the given mode number. In addition, a Modal Assurance Criteria (MAC) is created in the background and used to ensure that the desired mode is used in each run in the exploration.
  - 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 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.

Create Derived Responses

Use the Derived tool to create responses which are combination of existing responses.

Restriction: Derived responses are not available for Generative Design explorations.

From the Design Explorer ribbon, click the Derived tool.

Figure 1.

The Derived Responses dialog opens.
Enter a name for the response.
Build the expression in the following ways:
- Right-click on an existing force and select Insert from the context menu.
- Select an absolute or maximum function from the drop-down menu at the bottom of the dialog then click Insert.
- Enter mathematical operators into the expression, such as +, -, *, /.
Click Create/Update.
