help ANSYS Fluent FAQ

What is ANSYS Fluent used for?

ANSYS Fluent is an industry-leading Computational Fluid Dynamics (CFD) software used to simulate fluid flow, heat transfer, and chemical reactions. Engineers use it to optimize the aerodynamics of Formula 1 cars, improve jet engine efficiency, and design better HVAC systems.

What programming language does ANSYS Fluent use for User-Defined Functions?

User-Defined Functions (UDFs) in ANSYS Fluent are written in the C programming language. These UDFs are then dynamically loaded into the Fluent solver to customize boundary conditions or introduce custom physical models.

Can ANSYS Fluent run on multiple cores?

Yes, Fluent is highly optimized for parallel processing and can run HPC (High-Performance Computing) simulations across multiple CPU cores. Utilizing more cores significantly reduces the solving time for complex 3D transient models with millions of mesh elements.
