Unmatched Model Accuracy
GT-POWER has long been recognized for its high degree of accuracy in predicting the
behavior of complex engine related phenomena. At its core, the GT-POWER solver is based
on the 1D solution of the fully unsteady, nonlinear Navier-Stokes equations. Beyond this core
lie state of the art thermodynamic and phenomenological model solvers to capture the effects
of combustion, heat transfer, evaporation, in-cylinder motion and turbulence, and engine and
tailpipe out emissions, to name just a few. This combination of solvers provides for
unmatched model accuracy for both macro level quantities such as torque, bsfc, airflow, etc.,
as well as detailed micro level quantities such as crankangle resolved cylinder pressure
resulting from multi-pulse injection strategies, as well as emission specie concentrations anywhere in the system.
Includes FE solution of
in-cylinder temperatures
Vehicle model for
integrated engine/vehicle simulations
Directly coupled with
Simulink, Star CD,
Converge, Fluent and
other codes
Acoustics of intake and
exhaust systems
Input variables may be
specified as a map or
functional dependency
Flexibility to study any
valving concept,
infinitely variable VVT
and VVL, as well as
cylinder deactivation
concepts
Acoustics of intake and
exhaust systems (see
brochure on Acoustics)
Complete chemical
kinetics library (see

Aftertreatment)
Capable of Real-Time
execution (see brochure
on SiL, HiL, & Real-Time
Modeling)
These capabilities are
included in every
GT-SUITE license
3D Pre-Processors for Rapid Model Building from CAD
The 3D pre-processors GEM-3D and
GT-SpaceClaim enable rapid building
models from a wide variety of CAD file
formats, including importing, cleaning,
discretizing and exporting to GT-ISE.
In addition, ideas can be sketched and
simulated in these tools without making
CAD files
Beyond Basic Cycle Simulation
GT-POWER is licensed as an all-inclusive package containing many advanced modeling
features not found in other engine simulations. A full FE solver for in-cylinder temperature
and heat flux distribution, as well as a complete, fully flexible, detailed chemical kinetics
and aftertreatment library are just two of the many advanced modeling capabilities
included with GT-POWER at no extra cost.
