Particleworks is a Computational Fluid Dynamics (CFD) software package developed by Prometech Software, Inc. in Japan. It is based on advanced fluid dynamics analysis method known as the Moving Particle Simulation (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 2 different fluids, such as oil and water. 

Particleworks - Particle-based CFD software (Computational Fluid Dynamics)

In addition, Particleworks supports multi-GPU computing. Thus, it is capable of simulating from hundreds of thousands to millions of fluid particles, allowing it to simulate very large-scale models. As a result, when Particleworks is coupled with a Multi body dynamics simulation software package, it becomes suitable for co-simulation of CFD simulation and MBD simulation. And thus, through co-simulation with RecurDyn, you can further broaden the application scopes of both software packages. (Both of MBD and CFD Simulation)

Co-Simulation of Rigid Dynamics and Fluid Dynamics

RecurDyn’s unique ParticleWorks interface allows you to easily perform co-simulation of solid and fluid dynamics.


Key Features

  • Meshless (Meshfree) CFD software based on particle method
  • One single easy-to-use interface from CAD import to post-processing
  • Tight 2-way coupled simulation with RecurDyn (rigid and flexible bodies)
  • Surface tension (CSF model and Potential model)
  • Turbulence with the hybrid model i which LES(Large Eddy Simulation) is combined
  • Heat transfer between solids and fluids, temperature-dependent viscosity
  • Free surface flow, large deformations
  • Viscosity (Newtonian/Non-Newtonian fluids and high-viscosity fluids)
  • Air resistance using the external data (useful to analyze the mist or spray with air resistance)
  • Implicit/Explicit Methods
  • Various Boundary conditions (Wall, Inflow, Moving, Periodic)
  • Direct file import form CAD software
  • Optimized for the latest Multi-core CPUs and GPUs
  • Coupled simulation including fluid, powder and rigid body

Pre-processing / Post-processing

Particleworks allows you to directly import 3D data from CAD software for defining the volume boundaries. Various boundary conditions and material properties can be applied to imported data. You can view or output the simulation results in various formats.

  • Pre-processing
    • Import 3D data from CAD software (STL format).
    • Generate fluid particle sources and sinks (through circular, rectangular, or arbitrary shapes).
  • Post-processing
    • Contour plots.
    • Streamline plots.
    • Animation of fluid motion.
    • Output coordinates, velocity, pressure, shear rate, torque, etc. in various formats.
    • View or output the simulation results as image (JPEG / PNG), video (MPEG / AVI) or STL files.


Since the fluid dynamics solver uses the MPS method, it allows you to mix various material properties of fluid, rigid, and powder. (However, the rigid-powder mixing is not supported.)

The solver also allows you to calculate shear rate and torque, etc. from velocity, pressure, and temperature of fluid.


Optional Functions

Particleworks supports running its solver on a multi-GPU system. 2D fluid simulations are also available.
