1. GT-SUITE

Its a 1D system simulation tool

The complete GUI of GT-SUITE is explained below:-

GT-ISE is the main interface where models are built, simulation settings are declared. It is an environment where various components are brought into a project map and connected together linking the entire model as a whole.

GEM3D can be used to build models from primitive components like pipes, flowsplits, shells, catalysts, pumps, etc.

The separate COOL3D tool allows for 3D model building and automatic export of underhood cooling module models.

VTDESIGN is a graphical preprocessing tool for valvetrain and cam design. It has several capabilities,
which include:

• Cam design tool for creating/modifying cam profiles, using one of many methods: constrained polynomials, intuitive b-spline control of acceleration, or hybrid spline with low order constants/slopes/quadratics connected by splines.
• Dimension-by-dimension visual setup of the valvetrain mechanism. All 5 standard valvetrain types are supported, and profile entered can be cam shape or valve lift profile

Once a simulation is complete, results are viewed in GT-POST, a graphical interface that enables viewing and manipulating of the data collected from the simulation. GT-POST contains the following functions and more:

• Graphically based data post-processing
• Quickly generate 2-D and 3-D plots

GT-SPACECLAIM is a 3D CAD tool included with GT-SUITE. Key applications include:

• Extracting the inner/fluid core (negative) of a solid model
• Importing and converting common CAD formats to GEM3D and COOL3D
• Simplifying geometry to prepare a model for simulation
• Building solid geometry for simulation before production CAD files are available

USES OF GT-SUITE

GT-SUITE is a multi-purpose platform with many physical libraries, containing both fundamental and higher-level components. Using these components, engineers are empowered to build system models of almost unlimited variety.

These applications span various industries, and GT has developed, and continues to develop, specialized tools and components for all of them. To see what is available for each industry go to:

• ON-HIGHWAY APPLICATIONS
• OFF-HIGHWAY APPLICATIONS
• MARINE AND RAIL
• INDUSTRIAL MACHINERY
• AEROSPACE
• POWER TRAIN

To see all of the applications that have been created follow the links below which are separated into the following categories: (1) Integrated Systems, (2) Thermal Management, (3) Multi-Body Mechanics, (4) Propulsion Systems and (5) Fluid Systems.

MODULES

FLUID

There are several components based on which flow propogates. This medium helps in delivering the required matter to mechanical components

MECHANICAL

Components for transmission and like size shape (parameters) are altered

CONTROL

Sensors and detectors are used to measure the output performance of the product being controlled

THERMAL

Essential for transfer of heat components are needed

ELECTROMAGNETIC

Electric and magnetic components are needed for transmitting and receiving signals.
