RecurDyn offers the ability to analyze MFBD systems that interact with either granular (dry) particles or particle-based fluids. Granular solids, such as soil, sand or printer toner are modeled using RecurDyn/Particles which is based on the discrete element method (DEM). Fluid dynamics is available through co-simulation with the MPS-based CFD software of ParticleWorks. RecurDyn has an interface for ParticleWorks that makes co-simulation between them simple.

What is ParticleWorks?ParticleWorks is a computational Fluid Dynamics - CFD software package developed by Prometech Software, Inc. in Japan. It is based on the advanced numerical method known as Moving Particle Semi-Implicit (MPS) method. In this method, the fluid is represented as a collection of particles. This allows ParticleWorks to simulate the movement of fluids precisely and stably. Furthermore, it allows ParticleWorks to simulate free surfaces, as well as the interaction between two different fluids, such as oil and water. The mesh-free nature of MPS allows for robust simulation of free-surface flows at high resolutions, saving the time need to generate meshes for the fluid domain. ParticleWorks provides direct file import form CAD software to reduce costs associated with mesh generation that is required for conventional CFD software.
RecurDyn ParticleWorks Interface
RecurDyn has an interface specially designed for the co-simulation of dynamics of rigid bodies and fluids based on the MPS (Moving Particle Simulation) method.

RecurDyn has an interface specially designed for co-simulation of dynamics of rigid bodies and fluids. RecurDyn is the world´s first
commercial multibody dynamics software to offer such an interface. This interface allows you to simulate complicated fluid-solid interactions that were very difficult to simulate in the past. You can now simulate the coupled interaction between the two easily, so that the solid bodies and fluids affect each other´s behaviors.
Through the co-simulation with ParticleWorks, the analysis of the coupled interaction between a mechanical system and a fluid can be analyzed. The streamlined co-simulation interface provides coupled MFBD-fluid simulation in a simple analysis environment.
Features of ParticleWorksParicleWorks allows you to analyze fluid behavior precisely and stably without mesh so taht the flow of liquid such as water or oil can be represented using the particles. It is possible to analyze free surface problems having contacts between two fluids such as water and air or moving-boundary problems. ParticleWorks also lets you analyze tens of thousands of particles and large scale analysis using GPU and compute-cluster hardware, making it ideal for the co-simulation with dynamic analysis and can further widen its scope through co-simulation with RecurDyn.
