Co-simulation with CFD and Particles

RecurDyn contains an interface specially for Co-simulation between RecurDyn and either fluid or granular dynamics software. This allows RecurDyn to simulate rigid body dynamics properly interacting with fluids or granular materials. RecurDyn is the world’s first commercial Multi-Body Dynamics software to offer such an interface. This interface allows you to easily simulate complicated fluid-solid interactions that were very diffcult to simulate in the past.

RecurDyn X EDEM

• Through RecurDyn’s Standard Particle Interface, setting up and running a co-simulation between EDEM and RecurDyn is very simple and intuitive.
• Particle results calculated by EDEM can be animated in the RecurDyn environment with the RecurDyn model results.
• Co-simulation of EDEM with RecurDyn achieves more accurate results, enabling deeper potential for analysis of the interaction between granular particles, such as gravel, stone, sand and mud, and the mechanical system or applied load.

RecurDyn x EDEM Co-simulation Examples

Co-simulations between EDEM and RecurDyn enable powerful analyses of material handling and off-road machine handling characteristics. For example :

• Automobile / Machinery Construction: Analysis considering the driving characteristics of special vehicles and equipment in off-road environment and the effect of bulk particles
• Mining industry equipment: Design and evaluation of equipment used for mining and transport of minerals
• Agricultural Machinery: Development and verifcation of agricultural machinery such as cultivators or harvesters
• Chemical and pharmaceutical equipment: Development and evaluation of equipment for mixing, coating, and transporting of various raw materials

RecurDyn/Particleworks Interface

RecurDyn has an interface specially designed for co-simulation of dynamics of rigid bodies and fluids based on the MPS (Moving Particle Simulation) method.

• Intuitive UI for easy modeling of co-simulation with Particleworks
• Animation of fluid particle results analyzed in Particleworks can be shown with the RecurDyn models within RecurDyn.
• Visualizing the outer line of fluid particles in 2D Profiles
• Measuring the number of fluid particles in a specified area for each time interval
• Captures the effects of the motion of the mechanical system on the fluid.
• Captures the effects of fluid behavior on the mechanical system.
• The effect of the behavior of the mechanical system can be seen in the surfaces and turbulence of the fluid.
