©2026 ANSYS, Inc. 4 Some key areas of the Ansys FreeFlow 2026 R1 enhancements An engineering tool for tackling complex free-surface flow applications SPH Fluids Simulation Periodic Continuous Injection Support: New implementation of Time Periodic control in SPH fluid inlets. Buoyancy force using fluid expansion coefficient: Natural convection on SPH models for predicting wall heat transfer rate at complex boundary (Beta). SPH Implicit Viscous Forces (Beta): New implementation of implicit calculation for viscous forces, for both Newtonian and non-Newtonian fluids. Flat Plate HTC correlation (Beta module): The characteristic length for the HTC correlation will now be calculated internally by the FreeFlow solver. Adaptive SPH Element Size. Optimization of the volumetric generation of SPH elements. Extend SPH Flowmeters: Measures the average of velocity (or temperature) of the flow over a given surface. Multiphysics Coupling Performance & Usability A new enhanced version of the integration between FreeFlow and Ansys optiSLang. Post-processing using Ansys EnSight.
