ANSYS FreeFlow 2026 R1

Ansys FreeFlow 2026 R1 is an advanced GPU-accelerated Smooth Particle Hydrodynamics (SPH) simulation software designed to address complex free-surface flow, splashing, and multiphase flow problems. As part of the Ansys 2026 R1 fluid product line, it supports both implicit incompressible and weakly compressible solvers, efficiently handling millions of particles. It is particularly well-suited for complex fluid engineering analyses such as tank sloshing, lubrication, and spray modeling.
Ansys FreeFlow 2026 Key Features and Benefits

    Powerful GPU Simulation Engine: Leveraging the powerful computational capabilities of graphics processing units (GPUs) to perform large-scale SPH particle calculations, significantly reducing the computation time for complex free-surface flow simulations compared to CPU-based methods.
    Dual Solver Modes: The software offers an implicit incompressible solver (suitable for high-precision, low-velocity scenarios) and a weakly compressible solver (suitable for high-velocity flows and highly dynamic conditions) to address diverse industry needs.
    Integration and Interoperability: Tightly integrates with Ansys CFX and Ansys Rocky, supporting multiphysics simulations across different physical fields (e.g., coupling SPH fluid results with particle dynamics simulations).
