TECPLOT ASCII Files
(extension ".dat")
TEC is a data directory which
contains examples of TECPLOT ASCII files. TECPLOT ASCII files are used by
the TECPLOT program, which is a visualization program for
technical data. Typically, a user has an application program
(fluid flow solver, engineering stress program, aeronautic
simulator, heat flow program), that produces lots of data.
The user must write a subroutine that packages this data into
a TECPLOT ASCII file format ( there are several, including special finite
element forms). Then the user can postprocess the data, and
display it, by running TECPLOT.
TECPLOT ASCII File Characteristics:

ASCII (although TECPLOT can also create and use binary data files
which typically have the ".plt" extension);

Color is not associated with the data, but can be added
during postprocessing by the TECPLOT program, or by associating
variables "R", "G" and "B" with data, for instance;

2D or 3D data, and can have time dependence;

No compression (except for the binary data format option);

Geometric data is stored, but the user can also store associated
quantities such as pressure, temperature, or velocity.

Data is grouped into zones whose meaning is determined by the user.
Animation is achieved by starting with each zone being a
"time snapshot", and displaying one zone at a time.
