Altair HyperWorks 2019 X Release Notes

HyperWorks X is the next generation of HyperMesh. The 2019 release contains a limited set of tools. All models, input files, and customizations for all solver interfaces are supported. HyperMesh database files (.hm) are compatible between HyperMesh and HyperWorks X.

New Menu System

All supported tools are organized in a ribbon, located along the top of the application. The ribbon allows you to quickly access tools and standard functions.

Enhanced model integration

Direct access to the model is provided through the contextual right-click menus.

Selection in the modeling window is synced with the Model browser and Entity Editor.

Enhanced display controls are available through the Show/Hide tool.

Geometry

Creation and editing
The creation of primitive points and lines is simplified via new graphical workflows.
Surface geometry is easily created and repaired with the Surfaces tools. Missing surfaces can easily be repaired using the Patch tool. Surface edges can be extended using the Extend and Cross Extend tools to close gaps. The Offset tool allows for both disjoint and continuous offset.
The creation of cubes, spheres, and cylinder primitives is easy with the Solids tools.
Prepare geometry for meshing with the help of the Split, Stitch, Imprint, and Boolean tools. Various methods to trim surfaces and solids using points, nodes, lines, surfaces, and planes are available in the Split tool. Surface connectivity problems can be fixed using the Stitch tool. For solid geometry, merging can be performed in various ways using the Boolean tool.
Midsurface generation
Midsurface generation and advanced editing can be performed with the Midsurface tool. Base Surfaces can optionally be defined with offset values before midsurface extraction. Next, Automatic midsurface extraction is performed. Semi-automated and streamlined correction of the midsurface plate information can be performed with the Edit Plates tool. Finally, the Pocket Imprint tool can be used to imprint pockets, fillets, and other geometry features from the source geometry onto the midsurface, to better capture thickness variations.
In addition, the standard geometry creation and editing tools can further streamline complex midsurface cleanup tasks.
Defeating and cleanup
Automatically find and defeature cuts, logos, fillets, and holes using the the Defeature tool. An advanced Batch mode tool is also available to perform multiple cleanup operations automatically.
Easily review and edit preserved edges using the Preserved Edges tool, in order to keep those edges from being defeatured during BatchMesher and auto cleanup.

Meshing

Surface meshing
The generation of surface meshes is possible using the General tool.
Perform both geometry cleanup and high-quality mesh generation with BatchMesher, taking into account geometric features and mesh flow considerations.
Generate a mesh suitable for tetra mesh generation, closely following the input geometry with CFD.
General meshes of different types are possible without having to know all of the inner workings of the mesh algorithms. Take full control with Advanced meshing, or allow HyperMesh to drive using Auto-decide meshing. Generate a Free or Mapped mesh to meet the needs of specific applications, or decide to optimize quality and generate a mesh that meets demanding quality criteria.
Direct midmesh
Generate a midmesh directly from input geometries, without having to generate or work with midsurfaces.

The Rebuild tool simplifies the process of remeshing existing meshes to generate a new mesh with good quality and flow. It is useful in many applications such as remeshing to adjust size, quality, and flow; changing to a different element type; adding, removing, or adjusting washers around holes; or locally correcting elements with bad quality or flow.

Thickness can be mapped from an input geometry to a shell mesh using both simple and advanced options from Map Thickness.

Tetra mesh
Creating a tetra mesh and remeshing a tetra mesh can be performed with the Tetra tools. Create a tetra mesh from closed volumes of shell elements, or from solid or closed surface geometry using the Create tool. Existing tetra meshes can also be locally updated using the Remesh tool.
2D Quality correction
Both automatic and manual tools simplify and streamline 2D mesh quality correction.

Element quality by QI Range is now available as part of the global Element Quality visualization mode, and is live during all model changes.

Automatically correct quality first using the Auto Quality tool. Manual correction using the Edit Elements tools can then follow in locations where automatic correction was not possible, or where more detailed control is needed. Problem areas can be automatically found and isolated using a simple model tour approach. Graphically see the quality change while using the Smooth, Split, Collapse, Move, and Replace tools. Edit local surface edge density values using the Density tool, or create missing elements to fill in small holes or gaps using the Create tool.

Local refinement
Locally refine 2D elements and attached 1D elements using either the Box tool or the new Auto Split tool. These are most useful for aerospace and marine applications, where specific transition patterns are required from the refined mesh to the existing mesh.
Fuse
Connect close proximity, overlapping, and intersecting parts with the Fuse tools. Automatically connect open shells to resolve penetrations/intersections, or prepare a BIW model for an electromagnetic analysis using the Open Shells tool. Create watertight volumes for CFD and thermal applications with closed shells using the Closed Shells tool.

Morphing

Morph mesh
Morph any mesh with the Morph Mesh tool. Nodes can be moved interactively using the Move tool, or by mapping nodes to lines, surfaces, elements, or other nodes.
Morph by selecting mesh edges and faces directly using the Morph Mesh tool. Edges and faces can be moved freely using the Move tool, or when mapped to selected targets.
Anchors and morph area are now fully recalculated after each moving entity is either appended or deselected using the Morph Mesh tool to allow for faster consecutive morphs with less manual selection, and more intuitive local morphing. This feature is enabled by default and can be turned off in the Options dialog.
Morph shapes
Save morphs as shapes using the Shapes tool. Any morphed state can be saved as a shape from anywhere, even inside other tools.
Record node movements performed with any tool (morphing or not) as a morph shape.
Save, preview, apply, export, import, and edit any shapes in your model using the Shapes table.
Create optimization design variables from any shape using the Design Variable checkbox inside the Shapes table.

Known Issues

  • With Windows 10 Enterprise 2016 LTSB Version 1607, dragging the right mouse button from the graphics to the application title bar causes the title menu to freeze. Pressing the Windows key will unfreeze this menu.

    This issue has been resolved in Windows 10 Version 1803.

Resolved Issues

  • Application crashes when updating morph volume edges on some large models.
  • Distance calculation issue when projecting nodes to some meshes with very deformed elements.
  • Elements connected to fixed layer morph constraint are sometimes folded when morphed.
  • Application crashes when creating tangency constraints between some adjacent 2D domains.
  • Product error displays when applying shapes using multiplier factors with a very large number of decimals.
  • Application crashes when saving a model that contains certain morph constraints of ‘along dof’ type.
  • Various general stability improvements and bug fixes.
