MotionSolve models are parametric and they can be built hierarchically. This means you can create libraries of parametric subsystems and reuse these to build your system model. MotionSolve has been developed in partnership with customers. So it has been thoroughly validated on real models for ease-of-use, scalability, accuracy, robustness and speed.

MotionSolve is an open solution. You can include flexibility effects by importing modal representations of finite element models, co-simulate with controls software and 1-D simulators that contain non-mechanical subsystems, include FMUs developed by third-party solution providers and connect to CFD codes to account for accurate aerodynamic forces. At the user interface level, you can create your own GUIs to instantiate systems and subsystems you created. At the solver level you can customize the physics of the model. Both the solver and the GUI have well-documented interfaces that allow you to customize and extend the solution.

MotionSolve offers powerful capabilities for multi-disciplinary simulations for system level analyses such as kinematics and dynamics, statics and quasi-statics, linear and vibration studies, effort estimation, vehicle dynamics, low frequency NVH and packaging synthesis. It also computes the necessary inputs for performing component strength calculations, weight minimization and fatigue life prediction.

The documented interface for MotionSolve has been used to develop a large set of custom tools for the automotive and heavy truck industries. The custom tools support:

  • Higher level modeling entities that describe parametric components and subsystems

  • System definition and assembly

  • Custom events that perform K&C studies, vehicle dynamics and rough road durability evaluations

  • Automatic report generation for all events

  • Design exploration with model and event variants.

MotionSolve has been successfully used in the automotive, aerospace, general machinery, white goods, packaging, heavy industry and wind energy industries.

Reduce Product Development Time and Cost

Build simple models early in the design phase and add complexity as the design evolves. MotionSolve supports a large set of modeling elements and a variety of analysis methods to facilitate this. Once you have a validated model, you can reuse it in many different contexts. Through simulation you avoid time consuming physical testing and get to the right answer earlier.

Accelerate Product Innovation

Evaluate the behavior of complex systems in realistic settings. Perform design of experiments (DOE) and stochastic simulation to characterize and optimize product performance. Use the loads computed by MotionSolve to reduce component weight, calculate component strength and evaluate fatigue life.

Reduce Design and Manufacturing Risk

Through simulation evaluate a wide variety of alternative concepts and designs very quickly and choose the best design. Moreover, as the design evolves easily validate updated designs with models that have already been built. Certify your products with MotionSolve!

Enforce Corporate Quality Standards

MotionSolve can capture your organization’s know-how as repeatable processes to ensure repeatability and consistency. You can customize the user interface to meet your needs and use automation to eliminate repetitive procedural tasks. You can standardize and share models, data and results with others in your organization.
