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