Simpack
Multibody system simulation software
Simpack Overview
Simpack is a general purpose Multibody Simulation (MBS) software used for the dynamic analysis of any mechanical or mechatronic system. It lets you generate and solve virtual 3D models in order to predict and visualize motion, coupling forces and stresses.
Modules in Simpack
- Simpack PreEmpowers users to build a wide range of multibody models from scratch. It offers a rich selection of multibody modeling elements, such as rigid and flexible bodies, joints, forces, excitations, and sensors.
- Simpack SolverIt offers static and dynamic time and frequency domain solver options, emphasizing robustness, speed, accuracy, and unique real-time capabilities.
- Simpack PostIt enables the generation of 2D plots, 3D plots, and 3D animations, and data processing with an extensive library of filters.
- Simpack WizardAllows users to create full industry simulation processes based on a database of Simpack models to enable better model reuse, process standardization and automation.
Frequently Asked Questions
Can Simpack integrate with external tools like MATLAB for control system validation?
Yes. Simpack supports co-simulation with tools such as MATLAB/Simulink, connecting the mechanical model to a control environment for closed-loop testing. This allows teams to verify how a system responds to operator inputs and confirm that individual control circuits do not interfere with one another, all before any physical hardware is built.
How is Simpack structured, and what are its core modules?
Simpack is built around four base modules covering the full simulation workflow: Simpack Pre (model setup), Simpack Solver, Simpack Post (results analysis), and Simpack Wizard. Together they provide a high-performance multibody system simulation (MBS) environment suitable for a wide range of engineering applications.
Can Simpack be tailored to specific industries or engineering domains?
Yes. Simpack offers application-specific add-ons including Simpack Automotive, Rail, Flex Modal, Gear Pair, EHD, Rolling Bearing, Realtime, and many others. Teams can deploy only the modules relevant to their work, keeping the toolchain focused and efficient.
What are the main benefits of Simpack's modular architecture?
The modular design lets teams build a simulation environment matched precisely to their needs. The core solver delivers accuracy, robustness, and speed for any MBS application, while add-on modules layer in domain-specific functionality, such as flexible body dynamics or bearing simulation, without adding unnecessary complexity.
