Entities and Solver Interfaces
A solver interface is made up of a template and a FE-input reader.
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.
Model Build and Assembly
Create, organize, and manage parts and subsystems.
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.
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.
Axisymmetry
Reduce a full 3D model with axisymmetric surfaces while accounting for imperfections.
Concept Modeling
Tools and workflows that are dedicated to rapidly creating new parts for specific use cases, or amending existing parts. The current capabilities are focused on stiffening parts.
Crash and Safety
Tools used for crash and safety analysis.
Airbag
Use airbag folder utilities and export a resulting airbag in a Radioss deck.
Aerospace
Essential utility tools developed using HyperMesh-Tcl.
Aeroelasticity
Import an aeroelastic finite element model with Nastran Bulk Data format.
Certification
Framework to plug certification methods to assess margin of safety from the model and result information.
PhysicsAI
Use PhysicsAI to build fast predictive models from CAE data. PhysicsAI can be trained on data with any physics or remeshing and without design variables.
Results Data in HyperMesh and HyperView
Results data can be post-processed using both HyperMesh and HyperView.
Developer
The Developer ribbon contains tools for automation and customization.
Plot Data in HyperMesh and HyperGraph
Plot data can be post-processed using both HyperMesh and HyperGraph.
Multibody Modeling in MotionView
MotionView is a general pre-processor for Multibody Dynamics.
- MotionView Overview
  MotionView is a general pre-processor for Multibody Dynamics.

      - Build a Heavy Truck Model
        The vehicle library is installed as a part of the MotionView installation.
      - Build a Front Suspension System Model
        This section explains briefly how to build and generate reports for a model built in the Truck Library.
      - Build a Rear Suspension System Model
        This section explains briefly how to build a rear suspension model. The procedure is similar to building the Front suspension model.
      - Build a Full Truck with Drivers Model
        This section briefly explains a Full truck with driver model.
      - Front Suspension Systems
        Front suspension supports the wheels in the front with the help of a solid axle. The front suspension stabilizes the vehicle to the road and helps to absorb the bumps of the road. There are two types of front suspension used in the Truck Library.
      - Rear Suspension Systems
        Rear Suspension supports the rear wheels with the help of a solid axle. There are three types of rear suspensions in the truck library.
      - Frame – Ladder - Rigid
      - Steering Subsystems
        The steering system mechanism permits the driver to guide the truck along the rod and turn right or left as desired. The steering mechanism includes the steering wheel which the driver regulates the steering gear which converts the rotary motion of the wheel into straight line motion.
      - Shock Absorber Systems
        The Shock Absorber system models a conventional shock absorber and the bushings at the top and bottom of the shock.
      - Stabilizer Bars
        The stabilizer bar helps to control body roll on turns. The Assembly Wizard allows selection of two types of stabilizer bars, single piece and two piece.
      - Jounce and Rebound Systems
      - Engine Systems (Powertrain)
      - Driveline Systems
    - Two-Wheeler MDL Library
    - Suspension Design Factors
      When you build front or rear vehicle models using the Model Assembly Wizard you can add analyses using the Analysis Task Wizard that include output requests for Suspension Design Factors (SDFs) which are useful for assessing a suspension’s kinematic and compliance characteristics.
