| ALE (Moving and/or Rotating Boundaries) / Overset mesh / Dynamic ALE |
SC/Tetra is equipped with ALE (moving and/or rotating boundaries) which enables simulating airflow caused by a moving object. This can include rotating fan blades or cars passing by one another.
SC/Tetra is also equipped with an overset mesh function which allows different sets of meshes to overlap. This enables an object to move freely without having to generate and eliminate mesh which is usually a very complicated process.
In addition, the dynamic ALE function enables an object to translate or rotate in response to a force caused by surrounding airflow.

| Free Surface
Analysis (VOF Method) |
 The
free surface analysis is a method used to capture the
boundary geometry between gas and liquid. This
method is useful for analyzing liquid surfaces exposed
to air or air bubbles in the liquid. The free
surface function can be used in conjunction with other
functions. The free surface VOF method and overset
mesh function have been combined to enable simulation of
a solid object breaking the surface of a liquid.
This can simulate an object dropping into a liquid or
blades of a paddle moving through water. |
| Human Body Thermoregulatory Model (JOS) |
 The
JOS Thermoregulatory Model was developed by Prof. Tanabe at Waseda University. JOS calculates the human body skin surface temperature by considering energy transportation using a detailed vascular system model and physiological characterization of the human body. At the same time, JOS also considers heat and moisture generated from the human body and reflected to the surrounding environment.
JOS accounts for changes in metabolic rate (e.g. from an
active state to a resting state) such as a person
getting into a car. JOS will calculate the change
in body temperature over time. |
| Electric Current (Joule Heating) Analysis |
Joule heat generated by an electric potential can be predicted and used as the boundary condition for an electrical heating wire. By specifying the electric potential at each end of the wire, electric current density, and electrical. conductivity, the electric potential field and heat flux at an location can be predicted.

| Cavitation |
The cavitation function predicts cavitation due to pressure changes in the fluid. While SC/Tetra does not generate vapor due to cavitation it can predict where cavitation may occur.
|
| Aeroacoustic Analysis |
|
SC/Tetra is equipped with the following three acoustic analytical functions:
1) Decomposition of a flow and associated acoustic fields and use of the acoustic
analogy method for noise prediction at a far field observing point away from the noise source,
2) Weak compressible flow model for resonant sound, and
3) Sound source detection method for detecting a sound source.
Aeroacoustic Analysis is usually calculated using LES (Large Eddy Simulation). However, sound source detection analysis can be calculated using the k-eps turbulence model and steady state analysis.
