  • 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. 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.
