Capture the Most Sophisticated Physics

Extend the physics of multi-body systems by including more complex attributes, such as linear and nonlinear flexible bodies for increased elastic realism, as well as stress and fatigue assessments, easily applying existing finite element (FE) models from Altair® OptiStruct® and Altair® HyperWorks®. You can also include automated contact between 3D CAD geometry, model friction, and clearance in joints.

Strength and Fatigue Life Calculation

MotionSolve also lets you build accurate system-level models of your equipment. Exercise the model through a series of tests to generate precise component load time histories. Apply these loads on detailed FE representations of components for strength and fatigue calculations. Additionally, perform topology optimization with realistic loads to minimize weight while satisfying stiffness and other strength targets.
