What's New

Aero workspace plane

Streamlined Aerospace External Aerodynamics Simulations

An aerospace-dedicated workspace tailors the user interface to external aerodynamics simulations and streamlines the workflow with built-in atmospheric conditions, optimized solver settings, relevant input and output parameters, and more.

Rocky Multi CPU

Multi-GPU Fluent Solver

A brand-new Multi-GPU Fluent solver (beta) accelerates steady-state CFD simulations, with results showing 4 high-end GPUs provide the same performance as more than 1,000 CPUs. Cost savings can be seen with a 4X reduction in power consumption and consistent hardware savings as well.

Fluent accoustics monopoles

Efficient and Advanced Acoustics Simulations

Efficiently run acoustics simulations in Ansys Fluent with the new sponge layer treatment and perform sophisticated analyses with sound composition and runtime Discrete Fourier Transform (DFT) framework.

Icepak cooling

Advanced Electronics Cooling

Perform advanced electronics cooling analyses that can include condensation, evaporation, and more, with a new printed circuit board (PCB) model that enables the import of Ansys Icepak settings.

Fluent Meshing part

Ansys Fluent Meshing Part Replacement

Efficiently add, remove, or replace geometry objects of your CAD model without having to remesh the complete model using the part replacement feature in the fault-tolerant meshing workflow.

Efficient Mesh Adaption

Efficient Mesh Adaption

Solve simulations more efficiently with new mesh adaption method options: Hessian error-based adaption, which accounts for strong and weak features, or anisotropic adaption, which adapts the mesh in one direction reducing the overall cell count.

  • Streamlined Workflows
  • Battery Modeling
  • Electric Motor Cooling
  • Turbulence Modeling
  • Multiphase Flows
  • Combustion Models

Accelerate your pre- and post-processing with streamlined workflows for meshing and application setups.

Fluent has customizable, task-based workflows for pre-processing to help accelerate the process of generating a high-quality CFD-ready mesh. These workflows are for both clean and dirty CAD. Application workflows are streamlined to help reduce the amount of clicks and panels a user has to deal with. These workflows include multiphase modeling, batteries, shape optimization, aerodynamics and more.

Advance your battery design and safety with rapid, accurate simulation. Electrochemistry can be used for age and life prediction. Battery thermal management and runaway can be simulated to ensure top performance and safety. A reduced order model (ROM) can be created by extracting key thermal characteristics to analyze temperature in seconds.

Electric motor cooling is critical as you move to higher power, high-efficiency equipment. Fluent can be used to find the appropriate cooling mechanism for an electric motor. Optimize this method, whether it's natural, water or spray cooled, to ensure motor efficiency is not impacted and magnets are not damaged.

A wide range of turbulence models are available to choose the right model for your application. Fluent offers a wide range of turbulence models including the industry-leading Generalized k-ω (GEKO) model. GEKO is a revolutionary concept with tunable coefficients that can be adjusted to different flow regimes.

Accurately simulate multiphase flows including gas-liquid, liquid-liquid, gas-solid, particle flows and even DEM. Different modeling approaches are needed as you move from single to multiphase flow applications, and Ansys understands this. To help accurately predict these challenging flows, we offer a wide range of models for gas, liquid, solid, particle flows and even DEM to get you the most accurate results.

Accurate combustion models allow you to gain insight into system performance and flow phenomena.

Assuring you have accurate combustion is critical for the precise mix of turbulence, chemistry and the interaction between them. Fluent offers accurate and validated reacting flow models for your combustion applications.

Accurately predict interactions between fluids and solids from pressure and/or thermal loads. Solve your fluid-structure interaction challenge to make sure your product is safe, reliable and optimized. Fluent can solve FSI problems standalone and couples with Ansys Mechanical for the most complex simulations.
