Altair MotionSolve New Feature Overview
View a high level overview of the new features available within MotionSolve 2019.


MotionSolve - Durability & Comfort Simulations
Our goal was to help engineers developing ground vehicles to determine fatigue life of components and improve driver comfort. Vehicle-specific simulation events have been added or streamlined to closely mimic standard physical tests performed in a lab (such as with N-post shakers) or on a test track.


MotionSolve Examples Library
The MotionSolve examples library has been added to provide users with resources to learn MotionSolve on real world type models.


MotionSolve - General Machinery Solutions
Our goal was to help users more easily build and simulate complex systems. To this end, we have added a library of higher-level modeling elements including cables, pulleys, and winches; linear actuators, struts, & rods; as well as gears and cams – obviating the need for users to separately define parts, markers, and joints for these elements.


MotionSolve - Generic Modeling Improvements
Many other enhancements in this release were designed to enable users to assemble and solve models to evaluate product behavior much faster, especially for vehicle simulations.


MotionSolve - System Design Solutions
Much of the MotionSolve and MotionView multi-body modeling and simulation technology has been incorporated into Inspire Motion to enable system design closely tied to 3D CAD geometry.

Altair HyperStudy Model Linking
Workflow and user interface changes have been made to the Model Resources dialog to streamline the experience by providing a clearer visual representation of the run’s directory structure.  This will make setup and review more intuitive.


Altair HyperStudy System Reliability Optimization (SRO) Method
System Reliability Optimization (SRO) is a new, highly efficient reliability based design optimization (RBDO) method.  This new method requires a reduced number of runs, and allows reliability constraints to be applied to not just the individual failure constraints but to the overall system reliability.

Improving Vehicle Performance with Multi-Body Simulation
Learn about the special capabilities available for vehicle simulations (cars & trucks) with Altair MotionSolve™

Philomec
Canadian start-up company Philomec specializes in mechanical engineering services that helps companies design and optimize their products using mechanical and biomechanical FEM simulation. Their creation of customized, validated biomechanical models, and the analysis of simulation results by experts allows surgeons to choose the model of an implant and adapt surgical maneuvers to a specific patient, thus reducing the number of implants used, as well as the risk of complications. It is challenging to validate biomechanical models due to the complexity of materials, scarcity of experimental data, and the lack of representation of variability. The application of Altair HyperWorks for explicit multiphysics simulation provides a high-level of confidence in the validity and stability of the musculoskeletal models.
