Multibody Dynamics Software RecurDyn

RecurDyn's intuitive and sophisticated GUI runs on the Windows operating system.RecurDyn includes various libraries of bodies, joints, and forces for rigid body modeling as well as various contact libraries that enable you to easily model mechanical systems. The rigid body solver, which is based on a recursive formulation, can perform dynamic and static analyses (and others) quickly, accurately, and robustly. RecurDyn also includes various functionality to aid in the analysis of the results such as 3D animations and plots.

Intuitive UI

The UI allows designers to perform modeling quickly and conveniently.

High-Performance Graphic Engine

The MBD-optimized graphics engine easily manipulates complex models.

Easy Modeling of Rigid Body Geometry

High compatibility with CAD software because of the embedded Parasolid Kernel (Imports CAD data in Parasolid, STEP, IGES, STL, ACIS, CATPart, and CATProduct formats) Support for geometry creation and editing (even for imported geometry)

Fast and Accurate Solver

The recursive formulation and the implicit G-Alpha integrator perform simulations quickly, accurately, and robustly. The contact algorithms of RecurDyn are exceptionally robust, enabling the analysis of problems with complex contacts.

Fast and Convenient Post-Processor

The animation and plot outputs allow you to easily and intuitively examine the results of a dynamic analysis, such as the magnitude and direction of the displacements, velocities, accelerations, and forces.

The Most Advanced Contacts in the Industry

  • Contact elements based on Hertzian theory (Nonlinear stiffness)
  • Consideration for friction effects (Kinetic friction/Static friction, Linear/Nonlinear)
  • Easily definable contact among multiple bodies
  • Noise reduction of contact forces through a smoothing algorithm
  • Magnitude and direction of contact force displayed on the screen
  • Multiple, distributed contact forces displayed (Geo Contact family)

General purpose (Universal) Sensor

Capable of modeling two types of general-purpose sensors (box and laser)
