ALTAIR MotionSolve




Simulating real-world physics and accurately predicting system behavior is the key to obtaining maximum value from CAE software. It involves intelligent modeling assumptions, choosing the right numerical solution algorithms and carefully examining the results to ensure that they are meaningful.

MotionSolve is a next-generation, multi-body systems analysis software based on a revolutionary new formulation technique. It provides analysts and designers with a broad selection of modeling entities to accurately model complex mechanical systems with minimal assumptions. The robust software is especially tailored for models containing a number of large, flexible bodies. It employs numerically stiff solution algorithms that are well suited to accurately solve a wide variety of problems. Finally, its availability within the HyperWorks suite provides users with an unmatched, built-in capability to analyze and evaluate system response.



Altair MotionSolve Benefits



Multiple Solution Types

Assess system design and performance with nonlinear dynamics, kinematics, linear, static or quasi-static studies.

Rich Library of Modeling Elements

Create complex, nonlinear systems to evaluate the dynamic behavior of systems, study vibration isolation, design control systems, perform packaging studies and generate realistic loads to predict component life and damage.

Flexible Body Simulation

Accurately predict loads and motions using flexible body elements.

Three-Dimensional Contact with Friction

Simulate mechanisms involving collision, rolling and sliding phenomena.

High Compatibility
