| Vehicle Aerodynamics |
| Cd and Cl are one of the values to determine a car’s performance. It used
to be experimented using a huge wind tunnel. However, you can now calculate
them with minimum error comparing with the experiment data. SC/Tetra can
even handle precise under-floor, pipes, and minor details due to its highly
tuned solver that consumes less memory than others. Cradle is dedicated
to continually improve the software’s accuracy and capability as well as
our technical support capability through carrying out simulations of leading
Japanese racing companies. |

| Passenger Comfort |
In addition to aerodynamics of a car body, cabin climate control is also
an important factor. You can calculate many situations you may face in
a car such as heating and cooling inside the cabin, being heated by solar
radiation, defogging and defrosting of a windshield and so on. SC/Tetra
is capable of handling very complicated geometry with sophisticated robust
mesher and low memory consuming solver. In addition, you can predicts the
comfortness of an individual in a car by using human body thermoregulatory
model
that considers the detailed vascular system and individual physiological factors. |

| Air Conditioner Ventilation Duct |
| The fluid analysis is also used for designing an air conditioner ventilation
duct. With CFD, it is possible to compute balanced and efficient air distribution
for the dashboard where space is extremely limited. |
 |
| Engine Room Ventilation |
The engine room ventilation such as the radiator ventilation is a critically important part. STREAM can calculate it at high speeds if rough shape is permissible.
For accurate models such an engine, a radiator fan, and other applications, it is suitable to compute with SC/Tetra. It can consider the pressure drop due to the radiator. |
 |
| Side View Mirror |
| In addition to the simulation of a car body aerodynamics, CFD is used for
many parts to see the characteristics of the airflow and its effect. For
example, a side view mirror has to do its job, reflecting the views, as
it needs to minimize the problems such as drag, droplets of water staying
at the mirror surface, aero acoustic noise and so on. SC/Tetra is able
to give the results of many design ideas in a short period of time. |
 |
| Manifold |
Intake and exhaust manifolds are simulated with steady state to determine
if they have uniformed pressure distribution. They can be also calculated
with transient analysis to determine if there is any reverse flow.
In addition to internal flow, an exhaust manifold should be thermally simulated considering the material and thickness of the manifold. |
 |
| Heat Exchanger (Radiator, Inter cooler, oil cooler, water jacket) |
| A CFD simulation of a heat exchanger such as a radiator considers two fluids like air and water (or coolant). CFD simulation is used to determine the efficiency of heat exchange resulting from the velocity of the fluids at the wall. It also enables to predict if the coolant has uniform flow inside the heat exchanger. |
 |
| Engine Valve |
| For engine valve analysis, the swirl ratio and/or tumble ratio which could
be an important parameter for fuel mixture can be computed. |
 |
| Torque Converter |
| A torque converter of an automatic transmission can be calculated with SC/Tetra
to observe pressure distribution as well as torque value that is produced
by rotating blades. |
