Highlights
Altair HyperXtrude is a powerful suite of solvers used by the industry for metal extrusion, polymer extrusion, friction stir welding, billet forging, and resin transfer molding. The main focus of the suite is on metal and polymer extrusion solvers.
Today's extrusion companies are forced to produce a higher mix of complex profiles in shorter product development cycles while simultaneously reducing their production costs. HyperXtrude is a simulation tool developed to analyze and validate the design of extrusion dies and process. The HyperXtrude solver enables production engineers to analyze material flow and heat transfer inside a die during extrusion to validate die designs which in turn helps to reduce or eliminate costly and time-consuming die trials. These solvers come with an easy to use CAD based interface.
All Solvers
All HyperXtrude solvers have been upgraded to H3D 13.0 libraries for exporting the results file in H3D format. This enhancement has many benefits, including access to new features in the libraries and internal tools to develop automatic report generation capabilities.
HyperXtrude for Metal Extrusion
An additional control to turn on/off the heating elements based on the temperature of the heating elements in addition to the thermocouple data is implemented.

Solver features are now classified as basic and advanced. The solver will checkout 25 HWU for basic features, and 50 HWU for advanced features. This will be automatically determined based on the input data. Basic features:

Results exported in H3D file used contain only the steps until bearing optimization converged. For example, if user specified 20 optimization iterations and solution converges in 7 iterations, result file will have solution only for 7 iterations. Now, the final seventh iteration is copied for to all the remaining iterations for smoothness of animation in HyperView and Click2Extrude.

The solver was enhanced to account for errors in data while setting up runs to enforce a limit on ram speed based on press tonnage. These changes enforce a minimum limit of ram speed and the correction applied to ram speed while enforcing press tonnage. Ram speed will not be lowered below the specified MinRamSpeedLimit (default is 0.1 mm/s) and correction applied to ram speed will be required to be higher than MinRamSpeedCorrection (default is 0.1 mm/s).
|
The solver was enhanced to account for errors in dead cycle time input data. If the user specified zero dead cycle time, the solver will automatically reset the number of dead cycle time steps to zero.
|
You can now modify the pset parameters MinStrainRate and MaxStrainRate used for minimum and maximum strain rate limits used in computation. The default values for these parameters are now set to 0.0001 and 1000.0. These values should work correctly for all simulations.
|
Improvements to strain computation was made to work correctly with the default strain rate limits. Results computed will predict the strain correctly in the billet regions.
|
Improvements were made to friction module to handle the slip condition after the bearing profile in the bearing region.
|
Improvements were made to particle traces module to export strain results to HyperView. In addition the number data points generated were reduced (one per element).
|
HyperXtrude for Polymer Processing
Improvements were made to residence time computations to accommodate for near zero velocities in the dead zone regions.
