Technological progress and the pursuit of new innovations make systems more and more complex. But there is no extra time available for development. For this reason, engineers are under pressure to confirm concepts as early as possible.
Dealing with complex geometries, large computational meshes, and the simulation of various physical phenomena are only a small part of the challenges that have to be overcome in CFD. In doing so, the user must not compromise between accuracy and speed.
Cost Pressure
Physical tests require prototypes, are time and personnel intensive and thus costly
Speed
Development time is not always balanced with development effort
Complexity
Increasing number of interacting and thus interdependent components
Accuracy vs. Speed
Optimization of one side is often at the expense of the other
Advanced Simulation
The creation of CFD simulation models is complex and can therefore be very time-consuming
Safety
Strict requirements for product functionality, quality, and safety must be met
FIRE M has unique preprocessing, solver and post-processing capabilities.
The software can handle any computational mesh, from hexahedral to polyhedral cells, including meshes with arbitrary interfaces. By combining basic finite volume technology for polyhedral meshes with the Immersed Boundary method, you can solve applications with any geometric complexity, as well as body and mesh motions. We call this unique approach the Embedded Body Method.
Solution apps, introduced with Release 2021 R2, provide guided workflows and templates that let you create complex applications in minutes.
FIRE M provides state-of-the-art turbulence modeling that accounts for the complexity of real flows.
The grid-independent modeling of heat transfer enables the accurate calculation of single-phase and multiphase flows, heat transfer between arbitrary fluid and solid regions, and temperatures in structures.
In addition, the software also supports the calculation of electromagnetic fields and the electrothermal behavior of batteries.
Easy to Use
Guided workflows and templates make it easy for users to work with the software. The AVL Simulation Desktop (SDT) provides a platform for data exchange within and outside your team as well as with other tools.
Data as the Basis for Development
Precise meshing and calculations deliver the most accurate results. This lets you make data-based decisions.
Work Efficiently
With FIRE M you can simulate multiple areas at the same time. Simultaneous simulation.
Embedded Body
Mesh setup in CFD is a challenging task. FIRE M therefore now integrates the "Embedded Body" into the standard finite volume method.
This immersed boundary approach simplifies the handling of geometrically complex bodies at the fluid-solid interface in terms of discretization of fluxes, boundary conditions, rate of change, gradient calculations, etc. The handling of the embedded body is extremely simple as it basically involves only two steps.
E-Motor Cooling App
Effective cooling systems are critical to the life of an electric motor. The Solution App offered in FIRE M, contains a guided workflow for solving oil spray cooling tasks.
Starting with CAD setup, mesh preparation and model setup, you are guided through the start of simulation to post-processing. This not only simplifies the entire process, but also speeds it up.
Thermal Runaway Simulation
To ensure the safety of battery systems, it is necessary to know when thermal runaway can occur in cells and how quickly it spreads to neighboring cells.
FIRE M provides the ability to analyze thermal runaway and propagation in detail under a variety of conditions. You can use the Virtual Twins to repeat the tests in exactly the same way and as many times as needed. In doing so, you are supported by the Battery Thermal Runaway app.
Fuel Cell Degradation Modeling
For fuel cells, too, the goal is to develop safe and long-lasting cells with constant performance. This requires detailed knowledge of cell aging and its causes in order to avoid potentially harmful operating conditions.
For PEMFC, FIRE M offers the possibility to study the following chemical degradation mechanisms:
- Carbon corrosion/carbon oxidation/platinum oxidation
- Platinum dissolution and repositioning
- Particle detachment and agglomeration
- Ionomer degradation

Electrified vehicles (EVs) are measured by their performance, range and cost. In addition, a compact powertrain design is desired, which has implications for thermal management.
The nearly silent operation of e-motors makes the vehicles quieter, but results in various noises and vibrations no longer being masked by the engine.
The body is probably the most multifaceted element of a vehicle. Largely responsible for the visual impression, it also provides protection against weather-related influences. In addition, it must be considered that where air flows, air noise is also generated. These noises can be perceived both around the vehicle and in the interior.
