Altair Inspire Extrude 2023 New Version Features
This update brings many exciting new features:
- Create dies for specific profiles
- Support bearing profiles with variable start points
- Enhanced impact of die deformation on bearing flow resistance
- Reference temperature and thermal stress
- Improved calculation of die opening gap
- Advanced mesh control options: for bearing, profile, and die
- Improved strain calculation accuracy
- More information: extrusion ratio and profile speed
1. Create dies for specific profiles
- Parametric-driven flat die creation (additional die types will be added later)
- Create dies through mouse clicks and parameter input.
- Supports a model creation history tree
2. Support bearing profiles with variable start points
- Inspire Extrude supports dies with different bearing start lines
- Achieved by defining different start lines
- Identify curves via the Bearing Start Curve feature
3. Improved calculation accuracy of post-deformation die impact on flow
- Implemented through the bearing reference surface of the die.
- During coupled calculations, after introducing die deformation, the effect of bearing angle changes on friction is included.
4. Reference temperature and thermal stress
- In metal extrusion, die deformation caused by extrusion force is more dominant than thermal stress. Now, users can ignore thermal stress in the analysis.
- Users can now specify a reference temperature for each die component, which improves the accuracy of thermal stress calculations.
5. Improved calculation of die opening gap
- Uses the improved Rotated Ray Tracing (RRT) method. This will be the default fallback method when Delauney Constrained Triangulation (DCT) fails.
- Generates a CSV file including the profile’s initial and final thickness. This helps understand profile shape changes caused by variations in exit speed.
6. Advanced mesh control options: for bearing, profile, and die
- Bias can be defined for bearing and profile meshes
- Dynamically displays mesh size based on different mesh layer counts and bias values
- Based on these settings, the software automatically adjusts mesh size and quantity for the profile section
- Users can define the mesh factor for the male die to change the mesh size on the load face
7. Improved strain calculation accuracy
- The new version improves dead-zone and strain calculation accuracy, and can capture dead zones more precisely.
8. More information: extrusion ratio and profile speed
- The software interface provides information such as extrusion ratio and profile exit speed
- These values are automatically calculated based on the model geometry and extrusion speed
- Definition and visualization of the Boiling Heat Flux Curve
- User model support (UDF) for grain prediction and heat transfer coefficient
- Improve quench warpage accuracy using residual stress
- Support importing material data from AMDC
- Add temperature-dependent Masuko-Magill model
- Add generalized polynomial viscosity model
1. Support importing material data from AMDC
- Licensed users of Altair Material Data Center can directly import relevant material data
- AMDC contains material data for 400+ materials suitable for polymer extrusion analysis
2. Add temperature-dependent Masuko-Magill model
Compared with the WLF and Arrhenius models, the Masuko-Magill model can fit material data better and extrapolate more accurately over a broader range. This model relates the viscosity at any given temperature to the viscosity at the glass transition temperature via two parameters, A and B.
3. Add generalized polynomial viscosity model
- Adds a generalized viscosity model developed by Altair to fit more complex material behavior; this model is more suitable for rubber-like materials.
- The viscosity fitting tool in the Compose toolkit can effectively fit viscosity data to the best-fit material model, including this generalized viscosity model.
Altair Inspire Extrude is easy to learn, enabling all engineers and designers to better understand—through simulation—how the profile characteristics and process variables of any specific metal alloy interact. With Inspire Extrude, even extremely complex profiles can be validated for manufacturability. Using geometry creation and simplification tools, CAD can be quickly simplified and modified within the tool, ensuring that potential profile distortion, deformation-induced damage, backend defects, transverse weld defects, seam weld issues, coarse grain size, overheating, profile quality, and poor surface quality can be corrected early in the development stage.
