What Ansys Fluent is

Ansys Fluent is computational fluid dynamics software for simulating fluid flow, heat and mass transfer, chemical reactions, and related behavior. It provides pre-processing, solving, and post-processing in one window, with models for turbulent, laminar, reactive, multiphase, combustion, battery, and fluid-structure interaction cases. Solvers include pressure-based and density-based CPU options plus a native GPU solver, with multi-GPU and high-performance computing integrations for larger simulations. Built-in tools cover shape optimization, one-click optimization, PyFluent customization, and user-defined functions. Fluent integrates with Ansys Mechanical, Icepak, and Motion, and offers automated meshing workflows including Mosaic, Rapid Octree, and Wrap Meshing. It is used in automotive, aerospace and defense, energy, and high-tech work. The hybrid product supports Linux, Windows, and self-hosted deployment, with 3D visuals and data export. Pricing is on request; a 30-day trial and free student access are listed.
