Ansys Fluids Simulation Software
Predict how fluids, particles, and heat behave before you build the prototype.
Ansys Fluids Overview
Ansys gives you a coordinated set of solvers that cover everything moving, mixing, or transferring heat in your design: turbulent and laminar flow, reacting and multiphase systems, particulate streams, and conjugate heat transfer in cabinets and enclosures. KETIV, an Ansys Select Channel Partner, helps your team pick the right tool for the physics in front of you, get it deployed, and put it to work. Talk to an engineer who runs simulations every day and go beyond the spec sheet.
Run the analysis your CAD review can’t
Whether you’re sizing a cooling system for a battery pack, hunting down a recirculation zone in a manifold, or trying to understand why an axial fan generates tones at part-load, the answer lives in physics that drawings can’t show.
The Ansys engineering simulation suite covers it: Fluent for general computational fluid dynamics, CFX for rotating machinery, Rocky for particles and bulk solids, and Icepack for thermal and HVAC. KETIV adds the people: licensing, deployment, and direct access to a US-based support team.
What you can solve with Ansys Fluids?
Ansys fluids software portfolio
Ansys Fluent
General-purpose CFD with turbulence, multiphase, combustion, battery, and FSI on a single, GPU-accelerated solver.- Single-window task-based workflow from meshing to post-processing
- Native GPU solver for steady, transient, and combustion runs

Ansys CFX
The reference solver for rotating machinery (pumps, fans, compressors, turbines) with mature transient blade row and harmonic balance methods.- Streamlined turbo setup with blade-design tool integration
- Transient blade row and harmonic balance for aeromechanics
- Real-gas property handling for steam and refrigerant cycles
Ansys Rocky
Discrete element method for granular and particulate flow at production scale, with shape-accurate particles and multi-GPU hardware support.- Tetrahedral particle representation for solids, shells, and flexible fibers
- Two-way CFD-DEM coupling with Fluent and FEA-DEM coupling with Mechanical
- Multi-GPU solver for runs in the millions of particles
Ansys Icepak
Conjugate-heat-transfer CFD for HVAC, data-center cooling, and electronics enclosures. Built on the Fluent solver, exposed through AEDT.- Body-fitted unstructured meshing for cabinets, racks, and ducts
- GPU solver support for steady and transient thermal runs
- Library of fans, vents, heat sinks, and TECs for fast model build
Customer story: IDEX Health & Science
IDEX designs precision fluidic components (pumps, valves, manifolds) for analytical and clinical instruments. The team uses Ansys Fluent to predict pressure loss, dispersion, and flow-path behavior before any glass or PEEK gets cut. KETIV supports the engineering team with licensing, training, and on-call simulation expertise so deadlines don’t slip while a user works through a meshing snag.

Frequently asked fluids simulation software questions
-
Ansys fluid dynamics simulations solve the Navier-Stokes equations numerically to predict how liquids, gases, and particles behave inside and around your design. Engineers use it for heat transfer, aerodynamics, mixing, combustion, fluid forces on structures, and thermal management — anywhere a physical prototype is too slow or too expensive to iterate on.
-
Both are computational fluid dynamics solvers, but they’re optimized for different problems. Fluent is the general-purpose CFD software, broad simulation capabilities across turbulence, multiphase flow, combustion, and battery physics, with a GPU-native solver. CFX is the reference tool for rotating machinery: pumps, fans, compressors, and turbines, where its transient blade row and harmonic balance methods are industry standards. Many teams license both and pick per project.
-
Yes. Fluent ships a native GPU solver for steady-state, transient, and combustion runs. Icepak supports GPU for thermal CFD analysis. Rocky has had multi-GPU support for years and is what makes million-particle runs practical. GPU acceleration is usually the biggest single lever for shortening CFD workflows without buying more HPC.
-
Yes. Fluent includes premixed, non-premixed, and partially-premixed combustion models for gas-turbine, IC-engine, and burner work. Couple to Chemkin-Pro mechanisms for detailed kinetics or use the Flamelet Generated Manifold (FGM) approach for production-speed predictions of NOx and CO.
-
Yes. Compressible flow (transonic, supersonic, shock-dominated) and incompressible flow (most liquid and low-Mach gas problems) are both handled, with pressure-based and density-based solvers selectable per case. Turbulent flow and laminar regimes are covered across the same solver framework.
-
US-based technical support from engineers who run CFD simulation every day. That includes deployment, training, optimization of your simulation workflow, and direct help when a project hits a wall, meshing issues, convergence problems, or matching solver choice to your flow physics. KETIV is an Ansys Select Channel Partner, with full access to Ansys resources plus a local team who knows your account.
-
Yes. Trial access is available for evaluation projects. Contact KETIV with a brief description of the fluid simulation problem you want to test and the team will set up a trial scoped to that use case.
