MotionSolve

MotionSolve can accurately simulate any mechanical system to predict forces, kinematics and dynamics of motion. The mechanical system may consist of rigid and structurally flexible bodies connected by various kinds of kinematic constraints and flexible connectors. Environmental forces and motion excitations drive the motion of the entire system.

MotionSolve is an integrated Multi-body solution to improve mechanical system performance. Through extensive customer partnership, MotionSolve is thoroughly validated for quality, robustness and speed. Based on superior numerical methods and scalable formulations, MotionSolve offers powerful modeling, analysis, visualization and optimization capabilities for multi-disciplinary simulations that include kinematics & dynamics, statics & quasi-statics, linear & vibration studies, stress & durability, loads extraction, co-simulation, effort estimation and packaging synthesis. Customers worldwide, in a wide range of industries from Automotive, Aerospace, Construction equipment to General machinery successfully use MotionSolve.

Benefits

 

Comprehensive solution for your varied multibody solution needs

Assess system design and performance with nonlinear dynamics, kinematics, linear, static or quasi-static studies. Create complex, nonlinear systems to evaluate the dynamic behavior of systems, study vibration isolation, design control systems, perform packaging studies and generate realistic loads to predict component life and damage.

 

Stay ahead of your competition using innovative solver features

In this fast paced era, you need a product that keeps up with your needs. MotionSolve keeps introducing innovative modeling elements and methods to simplify your complex multibody systems. Innovations can vary from novel formulation, modeling elements such as deformable curves and flexbody contact to all new customization of solver.

 

Perform system level analysis through co-simulation

There is ever growing use of hydraulics, pneumatics and controls in mechanical systems. MotionSolve is capable of working with detailed hydraulic, pneumatic and control models.

 

Robust and Accurate Solutions

MotionSolve is tested on a wide variety of industry specific problems, and is subject to very rigorous and stringent quality-control using state of the art testing procedures. You have a robust solution for different numerically stiff or non-stiff problems.

 

Reduce time to market

Bring the products faster to market using MotionSolve. MotionSolve is very fast and maintains accuracy even while solving stiff problems such as flexible multibody simulation, contacts and long duration durability simulations.

 

Capture your corporate standard practices through customization

Traditionally the two words “Customization” and “solvers” are not used together. MotionSolve is a highly customizable solver. From writing custom functions, custom messages to creating custom outputs, MotionSolve can help someone who is trying to set corporate standards by customizing the solver.
