What's New
View new features for Engineering Solutions 2022.2.
Get Started
Engineering Solutions is a modeling and visualization environment for NVH, Squeak and Rattle Director, Crash, CFD, and Aerospace using best-in-class solver technology.
Tutorials
Discover Engineering Solutions functionality with interactive tutorials.
NVH
Noise, Vibration and Harshness (NVH) is an important vehicle attribute that directly affects the customer experience.
Squeak and Rattle Director
Use the Squeak and Rattle Director tool to create evaluation lines, evaluate them and optimize the interfaces to eliminate squeak and rattle issues.
Crash
The Crash application offers a tailored environment in HyperWorks that efficiently steers the Crash CAE specialist in CAE model building, starting from CAD geometry and finishing with a runnable solver deck in Radioss, LS-DYNA and PAM-CRASH 2G.
CFD
HyperWorks offers high quality tools for CFD applications enabling the engineer to perform modeling, optimization and post-processing tasks efficiently.
Aerospace
Essential utility tools developed using HyperWorks-Tcl.
Interface with External Products
Solver interfaces supported in Engineering Solutions.
Entities and Solver Interfaces
A solver interface is made up of a template and a FE-input reader.
CAD Interfaces
Support provided by the CAD readers and writers.
Browsers
Browsers supply a great deal of view-related functionality by listing the parts of a model in a tabular and/or tree-based format, and providing controls inside the table that allow you to alter the display of model parts.
Panels
Panels contains pre-processing and post-processing tools.
Geometry
Create, edit, and cleanup geometry.
Meshing
Different types of mesh you can create in HyperWorks.
- Elements
  Elements are FE idealizations for a portion of a physical part.
- SPH Meshing
  Smooth Particle Hydrodynamics (SPH), Finite Point Method (FPM) is a technique used to analyze bodies that do not have high cohesive forces among themselves and undergo large deformation, such as liquids and gases.
- 1D Meshing
  1D mesh that allows accurate testing of connectors, such as bolts, and similar rod-like or bar-like objects that can be modeled as a simple line for FEA purposes.
- 2D Meshing
  A surface mesh or "shell mesh" represents model parts that are relatively two-dimensional, such as sheet metal or a hollow plastic cowl or case.
- 3D Meshing
  Volume mesh or "solid meshing" uses three-dimensional elements to represent fully 3D objects, such as solid parts or sheets of material that have enough thickness and surface variety that solid meshing makes more sense than 2D shell meshing.
- Mesh Controls
  Mesh controls are used to automate and streamline the meshing process.
- Check Mesh Quality
  Evaluate the overall quality of a mesh, and resolve criteria violations.
  - Element Quality Calculations
    After you build your model, calculate the quality of elements in a mesh.
    - How Element Quality is Calculated
      The quality of elements in a mesh can be gauged in many ways, and the methods used often depend not only on the element type, but also on the individual solver used.
    - Quality Index Calculations
      The Quality Index value is a function of twelve criteria with user-defined weight factors. Each criterion has five rating levels.
  - Element Quality View
    The Element Quality view allows you to investigate each specific element criteria, view a breakdown of all failed and worst elements, resolve all criteria violations at one time, and evaluate the over all quality of a mesh.
  - Check Element Quality
    After you build your model, check the quality of the elements in the model.
  - Create Mesh Quality Report
    Create an HTML mesh quality report for the current model or for multiple models.
  - Review Shell Thickness
    The Thickness view allows you to investigate the shell thicknesses in your model.
  - Check and Fix Boundary Shell Intersections
    Validate the input surface mesh before performing volume mesh generation using the Boundary Shell Checker.
  - Solid Mesh Optimization
    The Solid Mesh Optimization tool can be used to improve the quality of a tetra, hexas, and second order meshes with respect to several element criteria.
  - Check for Element Penetrations/Intersections
    Penetration is defined as the overlap of the material thickness of shell elements, while intersection is defined as elements that actually pass completely through one another.
- Edit Mesh
  Modify your mesh by detect holes, locating edges or features, refining mesh pattern, and so on.
Connectors
Create connections between parts of your model.
Model Build and Assembly
Create, organize and manage parts and subsystems.
Model Verification
Perform automatic checks on CAD models, and identify potential issues with geometry that may slow down the meshing process using the Verification and Comparison tools.
