Multibody Mechanical System Modeling

Learn about modeling multibody dynamic systems.

Attention: Available only with Twin Activate commercial edition.

Twin Activate facilitates the modeling of multibody dynamic systems (MBD) through equations and Modelica blocks. Twin Activate features co-simulation with Altair MotionSolve software.

Multibody Simulation with Modelica
The Modelica Standard Library includes a dedicated palette of multibody blocks.

Multibody Co-Simulation
MotionSolve enables the combined simulation of subsystems of mechanical plants with those of electrical/electronic subsystems, such as controllers. The co-simulation process enables communication and data exchange between Twin Activate and MotionSolve MBD models.
