Sessions and Report Templates
Set up sessions and create report templates.
Interface with External Products
Solver interfaces supported in HyperMesh.
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.
- Assembly Tools
  Create an assembly structure from a .csv file definition.
- Load/BCs Tools
  - PLOAD1 Create and Review
    Create and review pressure loads on 1D elements that are fully or partially loaded.
  - Map Force, Mass, Temperature
    It is convenient to apply aerospace loads and concentrated mass that is predefined at specific node ID’s from an Excel file. This requires carefully numbering nodes with specific ID’s, which is a standard practice in aerospace.
  - Line Loads
    Line loads allow total loads (forces and moments) to be applied in a distributed manner on nodes even though the load is applied on geometry lines or set of nodes forming ordered edges.
  - Connect Two Dissimilar Meshes
    Connect two dissimilar meshes using displacement constraint elements.
  - Window Pressure
    Aircraft windows are normally modeled with CROD elements around the hole of the shells. Constant pressure on the window area is applied by means of force distribution on the edge nodes.
  - Transform Elements
    Use the Transformation Tool to translate, scale, reflect or rotate elements with multiple numbers of copies, including properties and loads, attached to them.
  - Convert Elemental Pressure to Nodal Forces on the Same Model
    Converts the pressure load to be applied on shell elements to equivalent forces on the corner nodes of the selected shell elements.
  - Map Thermal Loads
    Map thermal loads from one model to another.
  - Implement RBE2 Connection with Assigned DOFs
    Implement a special RBE2 connection with assigned DOFs.
  - Field Looper
    Use multiple combinations of source files (in the form of CSV) and multiple target models (decks or HyperMesh .dbs) to realize field mapping for the creation of new loads, such as temperature and pressure.
  - Plot SPC/SPCD
    Use the Plot SPC/SPCD tool to display the SPC/SPCD assigned to the nodes in their relevant analysis (output) system. The tool shows the coefficients of the selected degrees of freedom (DOF) and the ID of the system associated to the node(s) where the constraint is applied.
- Connection Tools
- Spatial ID Manager Tools
- Display Tools
- Export Tools
- Set Tools
- System Tools
- Node Tools
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
Results data can be post-processed using both HyperMesh and HyperView.
Developer
The Developer ribbon contains tools for automation and customization.
Plot Data
HyperGraph is a data analysis and plotting tool with interfaces to many file formats.
Multibody Modeling
MotionView is a general pre-processor for Multibody Dynamics.
Media Files
MediaView plays video files, displays static images, tracks objects, and measures distances.
Tabulate Results
Use TableView to create an Excel-like spreadsheet.
Text Files
TextView math scripts reference vector data from HyperGraph windows to automate data processing and data summary.
Publishing and Reporting
Create, define, and export reports.
Collaboration Tools
Explore, organize and manage your personal data, collaborate in teams, and connect to other data sources, such as corporate PLM systems to access CAD data or publish simulation data.

Implement RBE2 Connection with Assigned DOFs

Implement a special RBE2 connection with assigned DOFs.

Restriction: Only available in the Nastran and OptiStruct user profiles.

From the menu bar, click Aerospace > Loads/BCs > RBE2 Filter.
Select the nodes.
By default you can select two nodes, node 1 (A) and node 2 (B).

Two nodes are generated, C and D in between node A and node B. Nodes C and D will have the same coordinates. RBE2 is created connecting node C as master and node A, B and D as slave with DOF 123. RBE2 connection is created with node D as master and node A and B as slave with DOF 456. SPC is created with clamped DOF 456 at node C.
Optional: Activate Multiple nodes selection.
RBE2 is generated connecting the selected nodes to a master node. The position is calculated by HyperMesh as the COG of the selection, and this node will be used as node A for further connection. This is the same approach used for Node 2 selection.
Select the numbering scheme for the nodes and RBE2s that will be created.
Optional: Select the name of components and the load collector where the newly created RBE2 and SPC will be located.
If this option is not selected, these entities are created in the current collectors.
