What's New and Overview of RecurDyn 2024
EnginSoft USA is excited to share with you the new capabilities and enhancements of RecurDyn 2024. For example:
- FFlex Static: A more stable static analysis can be performed for various models. In addition, various improvements have been made related to static analysis, including supported force display, supported contact pressure, show static animation option, and scenario output control.
- Linked Assembly: With the new Linked Assembly toolkit, the Assembly Bodies such as the Track Link, Chain Link, Belt Segment, and Passing Bodies such as Pulley, Sprocket, Wheel, Flange, and Guide, can all be created using CAD Geometry rather than the geometry from the specific toolkits.
- Geo Sphere Contact: Geo Curve 3D and Geo Sphere to Curve 3D are new contacts that are optimized for Curves 3D contact modeling. Geo Curve 3D Contact has parameters similar to those of the existing Geo Curve Contact 2D. However, it can be also used to simulate 3D phenomena by setting the Curve's thickness using the Radius field. It can be applied to both rigid and flexible bodies, and you can select either Curve or Circle as the Geometry Type in the Action Geometry.
- Buoyancy Force: The Buoyancy Force function that can calculate and apply buoyancy and flow effects has been added. You can create a Buoyancy force by selecting a reference marker to define the fluid surface and flow velocity direction, and a surface or solid that will be subject to buoyancy. Buoyancy can be applied to both rigid and flexible bodies (referencing a Patch Set).
- Gap Force: This new feature applies forces to both the Action Body and Base Body to maintain a user specified gap between the Action Body and Base Body. The gap force is used to represent the effect of a gap imposed by air or magnetic forces.
- JMAG RT: A new JMAG RT block has been added. The JMAG RT (*.RTT file) model is a 1D model of a motor's characteristics obtained from the JMAG simulation software for electrical device design and development. This allows models containing 3 phase PMSM motors represented in JMAG RT to be modeled in CoLink and enables the confirmation of control algorithms for such models, as well as the simulation of RecurDyn models that include the motor.
Calculating the Heat Transfer and Boundary Conditions of the Lubricant Within an eDrive Using Particleworks

This release also facilitates conjugate heat transfer analysis with improved capabilities for utilizing spatially distributed physical quantities as boundary conditions, supporting temperature, heat source, and heat flux. The graphical user interface (GUI) allows the visualization of physical quantity distributions, enhancing the analysis process.
Other notable additions include passive scalar calculation and an interactive Python console.
Particleworks 8.0 also incorporates a snow model based on the Mohr-Coulomb failure criterion, providing comprehensive insights into the behavior of Bingham fluid models. A new negative pressure model has been introduced to further refine simulations.
The software now offers improved connected inflows, enabling seamless connectivity between multiple inflows and outflows.
The addition of a dynamic contact angle model and a potential amplifier for near-wall particles enhances simulations in complex situations.
Lastly, the Release 8.0.0 introduces the integration of DEM-MPS co-simulations with volume exclusion effects.
With these powerful new features and improvements, Particleworks 8.0 empowers engineers to optimize machine design, analyze complex physical phenomena, and gain deeper insights into fluid dynamics and particle behavior.
Optimizing Machine Design with Specialized Belt, Chain and Gear Toolkits

RecurDyn Multibody Dynamics offers specialized toolkits to quickly model and simulate these, allowing engineers to evaluate various aspects of performance such as efficiency, load transferred to system components, transmission error, transient effects during start up, or failure conditions at high speed. Please join us for this webinar where we will demonstrate how the RecurDyn Belt, Chain and Gear Toolkits can help you analyze your system to achieve the best machinery design.
Multibody Dynamics for PTC Creo Interface for Simplified and Automated Flexible Body and Contact Modeling
The MBD for Creo Interface (CRIX) automates and simplifies the workflow of moving data from Creo to RecurDyn. It is very fast and easily exports an assembly from Creo as well as all the joints associated with the geometry, into RecurDyn. Working with contacts in RecurDyn improves the ability to model springs, gears, bearings, and many other industrial applications. Key advantages to this interface include:
- Easier to start modelling - take your assembly from Creo to RecurDyn in just a few clicks
- Preserves assembly structure
- Avoid duplicating work – re-use CAD constraints as MBD joints
- Keep geometry up to date – no need to remember what geometry you or a colleague changed
- Improved process reduces clicks by 90%
Understand, Predict, and Optimize Real-World Designs with Multiphysics Simulation
In the past, only one type of physics could be considered at one time and the models were coarse. As computer hardware became faster and the simulation software more capable, more detailed models could be used. However, these details models continued to lack the ability to study the interaction between different types of physics. For this reason, we advocate the use of multi-disciplinary technologies to provide engineers, at every stage of the product cycle, a clear picture of the interactions that define the overall product behavior. No matter how small, each part and process in the chain must be considered when creating robust, accurate, and reliable simulation models. Join our webinar on to learn how this multi-disciplinary approach can help your design process.
Optimize your Product Design
Simulation is a key piece of the product development process but part of a larger puzzle. Making the best use of all available human and compute resources requires a digital pipeline to contextualize information as it moves through an organization. Optimization tools such as Iliad fill this role by providing a platform to connect different software tools and data sources while visualizing their connections. Once a process is defined it can be automated in a variety of ways, from simple DOE testing to completely hands off optimized designs. Join us to learn how OmniQuest’s Iliad can help your business.
What's New and Overview of RecurDyn 2023
EnginSoft USA is excited to share with you the new capabilities and enhancements of RecurDyn 2023. For example:
- The performance of the Newton-Raphson Static solver has been significantly improved, and includes the calculation of linear and nonlinear flexible bodies. Some models can be solved much more efficiently by solving at discrete time intervals.
- Contact calculations are significantly faster due to algorithm improvements that have been developed over more than two years.
- DOE studies and system optimization can better include morphing geometry, with an improved geometry update function that considers the geometry hierarchy.
- A new bidirectional heat transfer function between the RecurDyn FFlex body and the Particleworks fluid particles enables multi-phase heat transfer calculations.
- Other enhancements include a new primitive geometry meshing function, a new Endless Simulation function, and improvements to the DriveTrain Toolkit and the Analysis Result Recording.
Evaluating a Gearbox Application Using Particleworks
Past methods required a physical prototype or test bench for gear mesh lubrication studies. The need for physical builds has now been replaced by Computational Fluid Dynamics (CFD) simulations. While not a trivial task, the studying of gear mesh or oil splashing is now a common practice. Particleworks takes this task even further by utilizing a meshless CFD tool to accomplish gearbox applications.

Modeling Springs Accurately Using Multibody Dynamics
In certain high-speed applications involving springs, obtaining accurate simulation results requires the detailed modeling of the springs beyond just the forces they exert between their endpoints. Increased accuracy requires that the mass of the spring be taken into account to capture the inertial effects of the coils. Capturing the true behavior also requires the modeling of contact between the spring coils and themselves and with other objects. This webinar will show you that by using a powerful Spring Toolkit, you can include all of the detailed behavior of springs to obtain accurate simulation results and improve product design.

Advantages of Using RecurDyn for NVH Analysis
RecurDyn multibody dynamics and multiphysics is a good platform for NVH because excitations that occur in a mechanical system are often nonlinear: 1) Flexible bodies with large deformations and momentum effects, 2) Nonlinear relationships with other types of physics. In this presentation we will validate the accuracy of this approach by the close correlation of the simulation and experimental results. The benefits of design changes to NVH performance are accurately identified in simulation because the inputs not being changed can be locked to be the same (unlike physical testing that has variability in test and design inputs). Noise that is emitted from flexible bodies can be estimated by the RecurDyn acoustics module. Such estimates can be used to suggest design changes (ribs or other stiffening) for reducing noise.
Multi-Physics-Enabled Fatigue Analysis Using RecurDyn/Durability
Fatigue can turn a perfectly functional part into an expensive warranty problem. Anytime a part experiences dynamic stresses it should be evaluated for fatigue performance to ensure it will last as long as intended. Fatigue analysis requires an accurate time history of strains in the component, and a multi-physics simulation is often needed in order to calculate accurate loads in the system. RecurDyn provides excellent multi-physics capabilities for mechanical systems that include assemblies in motion.
In this webinar you will see a refresher course on what fatigue is and how a part's expected lifetime is calculated. Once the basics have been covered you'll see how RecurDyn's Durability toolkit can help you make these calculations for complex real-world parts.
New Multibody Dynamics for PTC Creo Interface for Simplified and Automated Flexible Body and Contact Modeling
Uncertainty Quantification (UQ) is a set of Machine Learning (ML) methods that puts error bands on results by incorporating real world variability and probabilistic behavior into engineering and systems analysis.
Presented by Chris Garcia
Presented by Fabiano Maggio, Phd.
RecurDyn is commercial-off-the-shelf (COTS), open architecture, multibody dynamics software. RecurDyn also interfaces with additional COTS modules and enables the development of custom applications. Using RecurDyn as a software platform for custom simulations of mechanical systems yields lower purchase costs, development costs, and increases robustness. A case study will be presented that describes the use of RecurDyn as a platform for an updated version of the NATO Reference Mobility Model (NRMM).
The simulation of the NVH behavior is essential for certain types of gears and contributes significantly to the evaluation of gear optimization. The forced vibrations are calculated in the drive train, which arise from the excitation in the meshing and are transmitted to the housing as variable forces and moments at the bearings. The radiation power is determined for the housing thus stimulated, thus enabling an assessment of the noise behavior of the transmission.
We're here to help you understand Particle Method CFD Particleworks! This introductory webinar will cover how the CFD Method works, the comparison vs. traditional methods, advantages and disadvantages, and when Particleworks should be used in the design process.
Come see what's new in RecurDyn V9R4. We will be discussing enhancements such as GUI, MFBD, and Toolkits.
Thermal behavior of many systems, such as e-motors and pistons, are very important but difficult to model and simulate. This leads to increased development time and ultimately higher product cost. Particleworks uses a unique method called MPS which allows these systems to be modeled and simulated faster than conventional finite volume methods.
The goal of design is to develop a product using reasonable choices. Optimization is a method to make the best choices. This webinar will cover the setup of an optimization model, including design variables, constraints and objective functions. Techniques for the correct formulation of the requirements will be covered and various optimization examples related to multibody simulation will be introduced.
The dynamic behavior of a fluid-filled, flexible container transported on a manufacturing line along a conveyer is simulated, with the goal of optimizing the product transport time. The simulation is at the level of quad-physics, meaning that four types of physics are simulated together.
Particleworks is a mesh-free, liquid-flow simulation software based on the moving particle simulation (MPS) method, which is capable of complicated fluid simulations such as liquid dropping, mixing, lubrication, spraying, sloshing and splashing.
Creo 7.0 introduces Fluid Flow Simulation to Creo Simulation Live (CSL). But how do you know when to use CSL vs traditional methods? We demonstrate how to get the best value from each capability for fluid flow, thermal, structural and modal simulation capabilities directly integrated within your Creo environment.
