What is the MPS Method?

The Moving Particle Simulation (MPS) method is a formulation for modeling fluid dynamics for uncompressible fluids. It was developed by Dr. Seiichi Koshizuka, a professor at The University of Tokyo. In contrast with conventional CFD methods that require meshes, the MPS method models fluids directly using particles to represent the fluid. This allows for easily modeling the free surfaces of fluids and for modeling multiple fluid types together, along with the boundaries between these fluids. As a result, the MPS method allows you to model and simulate your target system easily and provides a remarkable advantage in simulation of free surface flows and complex boundary geometries.

In conventional CFD methods that use meshes, it is very time consuming to generate an optimal mesh, and it is very difficult to simulate free surface flows or complex boundary geometries.

However, the MPS method, which is a mesh-free method, can easily model and simulate not only those free-surface flows and geometries but also fluid splashes.

RecurDyn x Particleworks Interface 

RecurDyn contains an interface specially for co-simulation (2-way co-simulation) between RecurDyn and either fluid or granular dynamics software.This interface can accomplish the advanced coupled FE-CFD using the System analysis considering interaction between fluids and flexible bodies.
