EFFICIENT AND EFFECTIVE
FIRE M has become the industry
standard 3D Computational Fluid
Dynamics (CFD) tool for modelling
tasks in both combustion and electrified
powertrains. Our latest update
– 2021 R1 – adds extra features
and refinements to help with complex
and time-consuming activities
such as in-cylinder flow modelling.
Such tasks typically begin with the
definition of the engine geometry.
That’s why we’ve integrated our
Engine Component Finder into
FIRE M Engine. This allows you
to quickly analyze a given input geometry
and assign identifiers to all
parts, with just a single mouse click.
With this, the discretization of the
in-cylinder domain can be done
easily and fully automated. High
quality polyhedral cell-based grids
ensure swift modelling and accurate
simulation results.
“FIRE M Engine users can create
models in a tiny fraction of the time
previously spent, without compromising
accuracy,” says Philip
Lawatsch, Senior Software Developer
at AVL. “In this way, engineers
can make valuable contributions
to decision-making even in
the most densely packed development
processes.”
With the new FIRE M Engine, the
usually complex simulation setup
processes are also simplified, allowing
you to get up and running with
your modelling tasks quickly and
easily. When it comes to training
or experience, very little of both is
needed, enabling users of all skill
levels to perform CFD simulations.
The same is true when you want to
perform case studies or optimization
loops. FIRE M Engine allows models
N O . 1 2 0 2 1
to be fully parameterized. In order
to vary parameter values, arbitrary
case studies can be generated
and executed automatically. Scenario
and case tables document all changes
and it is always clear which data
is used when and in which context.
In the past, creating charts and figures
or assembling a report that
helps to make decisions was an
enormous effort. This is made much
easier with FIRE M Engine. Using
application-specific templates for
different engine types, expressive
reports can be generated in Power-
Point format with zero effort in a
minimum of time, with the engine’s
key performance indicators summarized
in a clear, compact way.
“FIRE M Engine allows us to focus
on the engineering task,” explains
Josef Ruetz, expert for virtual IC Engine
Development at AVL Powertrain
Engineering. “This is how
my team overcomes the challenges
of CO2 and emission reduction.”
Of course, any simulation is only
as good as its input data. FIRE M
Engine allows its users to provide
all required input through a unique
entry point, the “Project Data
Sheet”. This makes it easy for engineers
to verify data availability and
quality, but also to make changes
when looking into different operating
conditions and designs.
CLEANING UP COMBUSTION
FOR FUTURE MOBILITY
The demands placed on the ICEbased
powertrain have never been
greater, and today’s combustionpowered
vehicles must balance performance
with extreme efficiency,
cleanliness and, as always, cost.
With tools such as AVL FIRE M,
we can help you achieve this.
