PARTICLEWORKS

Next-Generation CFD Realized Through Particle-Based Analysis

Even Paste Mixing

Uniform Mixing and Stable Flow Analysis

ParticleWorks delivers precise fluid behavior analysis using a meshless, particle-based approach.

By eliminating the need for mesh generation, it enables the rapid analysis of complex phenomena—including free surfaces and moving boundary problems—directly from CAD geometry. This streamlined process drastically reduces simulation lead times.

Mesh-Free Fluid Simulation

Advantages of Mesh – Free Fluid Analysis

ParticleWorks utilizes CAD geometry directly, enabling immediate analysis without the need for mesh generation. This significantly reduces both preparation time and the overall workload for engineers.

Unlike traditional mesh-based CFD, MPS (Moving Particle Simulation) based analysis simplifies modeling and offers exceptional performance in handling complex free-surface and moving-boundary challenges.

Conventional Method (Mesh-based / Grid-based)

Domain-wide Mesh Generation: Requires mesh generation for the entire analysis domain.
Restricted Calculation: Calculations are performed only within the defined mesh regions.
Mesh Dependency: Free surface accuracy depends on mesh size; droplets smaller than the mesh cannot be captured.

Particle Method (Mesh-free / Particle-based)

Direct Fluid Modeling: Models the fluid itself as particles without the need for a mesh.
Property-based Simulation: Fluid properties are assigned to individual particles, which are generated specifically for the fluid volume (e.g., water column).
High-Fidelity Resolution: Captures subtle free surface variations and enables the calculation of droplets splashing outside the tank.

Fluid Meets Motion

Integrated Mechanical & Fluid Interaction

ParticleWorks brings real-world mechanical-fluid interactions to life through its powerful co-simulation with RecurDyn.

By calculating mechanical behavior and fluid pressure simultaneously, it offers a versatile simulation environment that easily links with diverse CFD data and external resources.
