Post-Processor
The postprocessor is used to visualize the data
calculated by the solver. SC/Tetra’s graphical
output capabilities are well suited for
qualitative and quantitative analyses while also
being capable of generating high-quality,
professional level visual displays. All the
functions of the postprocessor are bundled in
SC/Tetra making it a complete, stand-alone
software package and eliminating the need to
purchase additional 3rd party
software.
GUI
PHILOSOPHY
SC/Tetra’s postprocessor is equipped with a
multitude of functions. If a conventional GUI
(Graphical User Interface) was used, the
interface would be extremely complicated with
many dialogs boxes and menu choices. The novice
user good easily get lost within the maze of
options. To improve accessibility to all the
capabilities within the SC/Tetra postprocessor,
an “Object” concept was adopted. Using the
Object concept, individual functions can be
dynamically operated. This makes it simple for
novice users to conduct an analysis
AESTHETIC SENSE
After the engineering analysis is completed, the data must be presented to
colleagues, management, and/or customer. SC/Tetra’s postprocessor makes it
possible to create attractive animations and inspiring pictures that will
produce overwhelming impressions of the technical analysis.

BASIC FUNCTIONALITIES
Basic - VECTOR MAP
A vector map is a basic method for visualizing a
flow field. In addition to a vector
representation, the SC/Tetra can express the
velocity field using several other visual
methods.
Basic - CONTOUR MAP
A contour map is often used to visualize
pressures and temperatures (scalar quantities).
The translucent expression of a contour image
enables the user to see the temperature and
pressure distribution on an inside wall or
behind an object. Moreover, the user can see
inside an object by using a cutting plane that
can be moved freely. The most suitable color
gradation for the analysis or presentation can
be selected by adjusting the color bar.
Basic - MESH VIEW
 A
meshed image can be mapped onto a model surface
to display the surface mesh created by the
preprocessor. Very fine meshes are often crushed
or not even visible using many of the other
visualization tools commercially available. In
contrast, SC/Tetra’s postprocessor displays
these details with astonishing clarity. In
addition, every detail of the mesh on an
arbitrary cross section can be seen using the
"Block Display " function.
Basic - STREAMLINES
Streamlines are used to investigate the
trajectory of the fluid from arbitrary points.
Streamlines can be visualized using simple
lines, ribbons and pipes. Furthermore, contour
and vector coloring can be mapped onto the
surface of the streamlines. The user can use
particles or paper airplanes fly through
streamlines and trace them in animation.
Basic - ISOSURFACES
Isosurfaces enable displaying the surface of an
arbitrary parameter in addition to mapping an
arbitrary variable on the surface of the
model,. These can include both vector and
scalar parameters such as contours of velocity
(vector) or temperature (scalar). It is also
possible to cut off a plane object or a surface
object with an isosurface.
Basic - VARIABLE GRAPH OBJECT
There are several ways to draw a graph using the
variable graph object in SC/Tetra. Graphs can
be constructed for a variable on the crossing
lines between a plane object and a surface
object. Or a graph can be made for a variable
on the arbitrary locus on a surface or on a
plane object. Time series graphs of variables
(for transient analyses) can also be created.
Basic - INTEGRATION
In addition to the integration of a vector or a
scalar variable, the projected area (the area of
projected shadow of an object) can also be
calculated. Moreover, it is possible to
integrate a variable over a front surface
separately from the back surface when they are
overlapped at the same position. Values of an
arbitrary point can also be checked using the
probe function.

ADVANCED FUNCTIONALITIES
Advanced - OIL FLOW
Oil flow is the visualization of "oil" streaks
which are drawn using the velocity near the
surface. An oil flow can be shown on a plane
object, at an arbitrary position, as well as on
surfaces of a model.
Advanced - Variable Registration
Variable registration makes it possible to
create a new variable from variables that are
already registered. Differential operator,
scalar product, and vector product can be used.
Advanced - Volume Object
Scalar and vector variables can be
simultaneously displayed in the whole
computational domain using the volume object.
This enables the user to grasp an image of the
flow as a whole.
Advanced - Separation of Views
All displayed objects, such as planes, surfaces,
isosurfaces, streamlines and others, can be
extracted from the analyzed model and rearranged
outside the model for presentation
.
Advanced - Animation
Additional functions are available to create and
enhance an animation.
Advanced - Other Functions
The SC/Tetra postprocessor contains a vast array
of functionality in addition to those described
herein.
