Tire Contact Patch Force Graphics
Electric Power Assisted Steering (EPAS)
The car/light-truck MDL Library now includes an Electric Power Assisted Steering system. The steering assist is generated by an electric motor geared to the rack in parallel to the steering column. The assist torque is a function of the vehicle longitudinal speed and the wind-up in a torsion-bar in the steering column as a proxy for the driver’s steering effort.
The electric motor and torque boost curve are encapsulated in a model exchange FMU exported from Altair Activate. The corresponding Activate model (.scm file) is included with the FMU in Car/Light-Truck MDL Library, and may be viewed and modified with Activate.
Rider Entity and Positioning Tool
MotionView Python API (Beta)
MotionView now has a Python interface (beta release) for creating a model. Using the API, MotionView models can be created, queried and modified through Python. This functionality opens avenues for modeling and customization, leveraging the power and flexibility of the Python language.
The API documentation for each entity with examples is available in the MotionView Reference Guide.
Improved Graphic Performance
CAD Graphic representation and its memory usage has been improved. This results in better responsiveness to mouse manipulation such as Pan/Zoom/Rotate.
MotionSolve-EDEM Improvements
- Mesh refinement ability while transferring geometry to EDEM is now available for CAD Graphics in the EDEM Subsystem panel.
- A new "EDEM" menu is available. This menu offers all tools related to EDEM
under one umbrella such as:
- Creation of EDEM Subsystem
- Running MS-EDEM co-simulation in batch mode
- Generating H3D from EDEM results
Support for Compose Subroutine
The User Defined interface for all entities that support User subroutines has been enhanced to provide Compose scripts as a subroutine in a MotionSolve run.
Other Enhancements
- Data Summary Improvements
- A new search option and filters are available in Data Summary. The View
Options provides ability to:
- Sorted based on dependency.
- Filter for empty tabs and deactivated entities.
- Filter points that are referred to as Body CG.
- Forms
- Forms panel can now display an image. If the cell in the form refers to a File name data member that has an image file, the image will be displayed within the cell.
Resolved Issues
- Messages on status bar were not being updated during Import, Export and opening of models.
- Body data member of compliant joints were not updated after merging bodies.
- Certain contact models failed to obtain mesh in the MotionSolve XML due to the mismatch of component names between MotionView and mesh generating Hypermesh.
- An application error on browser scroll immediately after CAD import has been fixed.
- Certain unit configuration with MNF to H3D conversion resulted in improper flex data to the solver.
- An application error on creation of output for Contact entity has been resolved.
- Transfer to EDEM of CADGraphics defined in reference to markers other than Global Frame resulted in an application error.
- A template failure to recognize left or right-side members of a pair has been fixed.
- A change in dataset used by graphic resulted in undesired change in system topology. This issue has been fixed.
