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.
