AVL Fire

AVL FIRE™ M is a versatile multiphysics computational fluid dynamics (CFD) software designed for the analysis of single- and multiphase flows, reacting and non-reacting flows, heat transfer, and solid-state temperatures within single and multidomain systems. While broadly applicable, its primary use is in the development of various powertrains and their components. The software provides detailed visualization of flows around vehicles and objects, as well as heat transfer between fluid and solid domains, and temperature distributions within structures.

Engineers face challenges with increasing system complexity, cost pressures from physical testing, and the need for speed without compromising accuracy. AVL FIRE™ M addresses these by offering unique preprocessing, solver, and post-processing capabilities. It handles diverse computational meshes, including those with arbitrary interfaces, and employs the Embedded Body Method, combining finite volume technology with the Immersed Boundary method to solve complex geometries and body motions. Solution Apps, introduced in Release 2021 R2, offer guided workflows for rapid application creation.

The software features state-of-the-art turbulence modeling and grid-independent heat transfer calculations. It also supports electromagnetic field and battery electrothermal behavior calculations. The AVL Simulation Desktop (SDT) facilitates data exchange and integration with other tools, promoting efficient, data-driven decision-making.

Key features include:

• Embedded Body Method: Simplifies handling of complex geometries at fluid-solid interfaces.
• E-Motor Cooling App: Guided workflow for oil spray cooling tasks in electric motors.
• Thermal Runaway Simulation: Detailed analysis of thermal runaway and propagation in battery systems.
• Fuel Cell Degradation Modeling: Study of chemical degradation mechanisms in PEMFCs.
