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.
