Altair Inspire Extrude 2021.2.0 | 3.6 Gb
The Altair Engineering development team is pleased to announce the availability of Inspire Extrude 2021.2.0 is an easy-to-use tool for simulating metal extrusion, polymer extrusion, and friction stir welding processes to detect potential defects early in the product development phase and improve the process efficiency.
New Features and Enhancements 2021.2
The Inspire Extrude 2021.2 release includes the following new features and enhancements.
Modeling Choke in Bearing Using Reference Surfaces
Bearing regions for complex profiles are often designed with varying choke, parallel, and relief regions along the periphery of theextruded profile. Meshing this region accurately and automatically using triangular prism elements is difficult. In this release, the bearing surface from the die assembly is extracted and accurately surface meshed. The solver will automatically extract the choke information from the surface mesh. This enables greater success in automatic meshing. In this release, the bearing surface is extracted from the tool geometry. This feature will enable any reference surface (not from the tool geometry). In the image below, the bearing reference surface is shown in red, and it is extracted for the die geometry

Bearing Optimization Controls
The bearing correction nonlinear algorithm is controlled by two parameters: maximum correction iterations and the acceptable tolerance. Previously, users did not have access to these parameters and were using the default values. In this release, these parameters are exposed in the GUI, and users can modify them.
Temperature-Compensated Strain Rate
The temperature-compensated strain rate is also known as the Zener-Holloman parameter. It is more convenient to plot the natural logarithm of this value. In this release, Inspire Extrude results will include both the temperature-compensated strain rate and its logarithm as two separate results for ease of post-processing.
Batch Meshing Improvements
Models with a choke in the bearing regions require special meshing methods to mesh this region with triangular prism elements. This meshing is accomplished using HyperMesh. However, when these models included the tool assembly, there were issues in meshingthe whole model in HyperMesh instead of SimLab. This issue is addressed through improvements to the batch meshing process. This enables selectively meshing the bearing and profile parts in HyperMesh and the rest in SimLab.

Map Extrusion Results
Extrusion and Quenching analyses are connected. Profiles extruded from the press then go through quenching systems to cool the high exit temperatures of the die to room temperature and allow for subsequent heat treatment and finishing operations. Ideally, the exit conditions of the profile extruded from the die become the initial conditions of the profile entering the quenching systems.

Users now have the option when running a Quenching Analysis to consider the profile temperature and grain size from a previous Extrusion analysis in the quenching simulation.

Pin Deflection Analysis
FSW analysis is useful in understanding stresses acting on the welding pin and any pin deflection it may cause. In this release, Inspire Extrude will automatically launch the pin stress analysis after the FSW analysis using OptiStruct, and users will be able to post-process the results in Inspire Extrude itself.

Resolved Issues
The following issues have been resolved for the 2021.2 release:
Common features:
- Constraints Incorrectly Created in Local Coordinate System. The solver expects the constraints to be created in the global cartesian coordinate system. Sometimes, the constraints were created incorrectly on the part’s local coordinate system. This issue is resolved now by creating them directly in the global reference system.
- Option to Remove Imprints in Boolean Icon. Added “Remove imprints” Option to cloned Extrude boolean context: IEXT-2507
- A Symmetric Model gives Asymmetric OptiStruct results. The solver writes the loads on the workpiece-tool interfaces to perform the stress analysis using OptiStruct. These loads are computed by performing the extrusion analysis up to the specified convergence. The loss of symmetry could happen for a few different reasons, such as asymmetric mesh and numerical oscillations. In this particular case, the projection and mapping algorithm was improved to address this issue in the reported model.
- Incorrect Heating During Dead Cycle Time. The dead cycle time is divided into two parts. In the first part, the hot billet isoutside the container. Therefore, it should lose heat, and the container also should lose heat. The solver was showing the container gaining heat due to incorrect convection reference temperature. This issue is resolved by correctly setting the reference temperature.
- Truncated Status Message resolved.
Polymer Extrusion:
- Random Memory Errors. Sometimes, the solver was encountering random memory errors. Its underlying cause was identified and resolved.
