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.
