RECURDYN

Integrated CAE Solution Based on Multibody Dynamics

Built for Real Motion

Analysis for Real Motion

Mechanical system behavior depends not on simple calculations, but on how accurately real motion is reproduced.

RecurDyn realistically reproduces complex motions involving contact, joints, and flexible body deformation, enabling reliable design-stage decisions.

FAST AND ACCURATE

FLUID MOTION

Fast and Accurate
Dynamic Analysis

RecurDyn is designed to compute dynamic behavior of complex mechanical systems quickly while maintaining high accuracy.

It provides efficient analysis workflows even in development environments with frequent design iterations and condition changes.

All-in-One Simulation

End-to-End Analysis
in One Environment

By integrating the MFBD Solver and Pre-Post Processor, preparation, computation, and result analysis are unified into a single workflow.
