HyperXtrudeŽ 2015 introduces a new CAD interface for HyperXtrude solver and takes a giant leap to a direct CAD to solution approach. This approach automates and hides the meshing and data deck creation, and completely relegates it to the background. Hence, users can submit the analysis after setting up the model directly on the CAD geometry. In this release, steady state metal extrusion is supported.

HyperXtrude simulates material flow and heat transfer by solving the Eulerian/Arbitrary Lagrangian-Eulerian form of the governing equations. HyperXtrude uses residual error estimates and local error indicators to identify the flow domain contributing disproportionate shares of error in the real solution. Using the error information, the mesh in these critical regions can be redefined by either refining the elements (h-refinement) and/or enriching the interpolation order (p-enrichment). HyperXtrude uses a combination of these to provide a near optimal hp-finite element mesh to produce accurate results. The resulting adapted meshes are fully unstructured and anisotropic. HyperXtrude is built on the hp-adaptive finite element kernel ProPHLEX. This kernel provides a high level of modularity and modeling flexibility for creating highly customized niche applications for engineering design analysis. HyperXtrude can be customized for specific user needs.

Metal Extrusion

Speed and Performance: Now you can work with large models up to 4 million nodes on both ShiChuang and Linux 64-bit platforms.

Solver Accuracy: Improvements include cone prediction of profiles, especially for those with large variation in thicknesses.

Bearing Optimization: This module determines the imbalance in material flow at the end of the bearing region instead of the exit to improve the accuracy of the bearing optimization.

Mandrel Offset: In this release, you can mesh the model with the mandrel offset and the solver will account for this step in the computation. The advantage of including the mandrel offset is savings in time spent in CAD correction.

Grain Size Computations: A new dynamic recrystallization grain size model (DRX) accounts for the dependency of grain size on strain, and temperature-corrected strain rate.

Automatic Extraction of Flow Volume: A new one-click option extracts the negative volume for the tool assembly and greatly minimizes model preparation time.

Automatic Billet Creation: This option lets you determine a billet center from a die surface or edge. Specify center coordinates and estimate the upset billet length from the specified data.

One-Click Solid Editing: One-click editing lets you merge or connect solids with a shared, common surface at the interface of adjacent solids.

Geometry Cleanup: Access HX-Geom Cleanup from the Geometry menu to remove edges and sliver surfaces. This option greatly minimizes model cleanup time.

Specifying Billet Taper data: With the Billet Taper option, you can specify three types of tapers in your analysis (Axial taper, radial taper, and lateral taper). You can specify the Axial Taper in up to five zones where temperature can vary linearly with different gradients.

Starter Billet: Using the Billet Taper option, you can specify starter billets of different lengths and use a different ram speed for each billet. This data is relevant only for transient, multi-cycle analysis. You can specify up to 5 different initial cycles with varying billet length data. In addition, you can use different axial tapers for each of the initial cycles.

Super Alloy Extrusion Using Glass Lubrication: The Extrusion Wizard now supports glass lubricated (with glass pad and glass powder coating) extrusion. Glass lubrication is often used with nickel, titanium, and steel alloy extrusion (requires a custom solver version).

Fit Material: An improved Fit Material GUI in the HyperXtrude material database lets you specify material data interactively or via the DAT file.

Improve Mesh: The Extrusion Wizard provides an option to improve the mesh quality by remeshing the solids based on initially generated mesh.

Tool Deflection Analysis in User Units: The Tool Deflection Wizard now supports user units. For example, if you set up a model in British units, your results from OptiStruct will have displacements in inches and stresses in ksi.

HX Job Manager: Added support for this feature lets you submit OptiStruct runs on remote machines.

Polymer Extrusion

Performance Enhancements: Now you can work with large models up to 4 million nodes on both ShiChuang and Linux 64-bit platforms.

Automatic Extraction of Flow Volume: A new one-click option extracts the negative volume for the tool assembly and greatly minimizes model preparation time.

One-Click Solid Editing: The Merge option merges selected solids. The Connect option creates a shared common surface at the interface between adjacent selected solids.

Easy Geometry Cleanup: The new HX-Geom Cleanup option, accessed from the Geometry menu, lets you remove unwanted edges and sliver surfaces, and minimize model cleanup time.

Tire Extrusion Wizard: The Tire Extrusion Wizard is used to simulate the extrusion of tire treads. The model-setup feature lets you create geometry based on a given die configuration or user-specified solids. This feature includes support of multi-cut extrusion dies, specification of tread and die contours as symmetric or full contours, and automatic report-generation.

Improve Mesh: The Extrusion Wizard provides an option to improve mesh quality by remeshing the solids based on initially generated mesh.

Tool Deflection Analysis Wizard: Solve tool deflection analysis with OptiStruct. Second order elements are supported, as well as pressures and forces. Loads from a HyperXtrude analysis can be mapped. Contacts between die plates, temperature conditions and other boundary conditions are automatically created.
