What's New in RecurDyn v2025/26 - Highlights, Improvements and New Capabilities 

See valuable enhancements in the handling, measurement and CAD functions in RD/Professional and get to know the new parametric features as well as the new contact options.  

Stay tuned for new solver options and MFBD enhancements. You could check out those new capabilities with the help of some examples to integrate them in your daily work.

RD4AI I: Data Collection & Metamodels in RecurDyn

In this workshop, we will demonstrate how to systematically prepare and collect simulation data from RecurDyn to make it usable for AI applications. We will also take a closer look at metamodels that, based on previous simulations, can significantly improve computational efficiency — especially within FFlex. 

RD4AI II: From Neural Networks to Physics-Informed AI 

This session provides an overview of different AI approaches — from simple neural networks to Physics-Informed AI. We will explore which methods are already feasible today, how they can be trained with RecurDyn data, and where they can meaningfully enhance simulations. 

From Simulation to Sound – NVH Analysis in RecurDyn 

In this workshop, we focus on Noise, Vibration, and Harshness (NVH) analysis.  

We will demonstrate how transient excitations from multibody simulations can be transformed into acoustic responses. Using sound pressure level (SPL) evaluation, participants will learn how to assess and interpret the resulting sound for better design insights. 

Extending RecurDyn with Python and C# 

In this workshop, we will show how to connect Python to RecurDyn in order to automate workflows and extend simulation capabilities. In addition, we will demonstrate how to create custom user dialogs in C# to provide tailored interaction and improve usability. 

Advanced Tools for RecurDyn 

A hands-on RecurDyn workshop that uses domain-specific toolkits to mirror real engineering systems with specialized modules and proven methods, making recurring workflows faster, more consistent, and more accurate.  

The tools in this workshop are FBG.PulleyRope, FBG.MachineTool, and TMeasy.  

FBG.PulleyRope provides tailored elements for belts and ropes with pretension, friction, wrap, and slip to deliver stable simulations for tension and torque transfer results. FBG.MachineTool offers purpose-built components for axes, guides, drives, and flexible structures enabling quick setup and precise assessment of compliance, dynamics, and positioning accuracy. TMeasy supplies a realistic tire model that captures longitudinal and lateral forces under combined slip allowing credible vehicle maneuvers with high robustness. 

Unified Modeling Approach for Repetitive Structures 

The toolkit Linked Assembly extends RecurDyn with a unified chain modeling suite. It supports modeling all chains (energy chains, tracks, drive chains, steel chains, bucket chains, anchor chains, timing chains) as general chain mechanisms. Unified modeling across different chain types with a common core, reduced integration effort. Improved consistency in coupling, runtime computation, and post-processing of chain mechanisms.

Parameter and Design Optimization in RecurDyn 

RecurDyn’s built-in toolkit for efficient design optimization, combining DOE, surrogate modeling, robustness, and reliability analysis with minimal simulations. 

This workshop provides a hands-on introduction to sensitivity analysis and various optimization methods using simple RecurDyn models.  

Thermal-Structural Analysis with RecurDyn FullFlex Thermal 

FFlex Thermal enables thermal-structural analysis of flexible bodies in RecurDyn, accounting for heat transfer, frictional heating, and feeding temperature effects into dynamics to capture thermal expansion and stress.  

This workshop covers the heating and expansion of a structure due to friction-induced energy input, demonstrated step by step in a RecurDyn MFBD model from setup to evaluation.
