philippemiron/tecplot-binary-read: Tecplot parser to read binary format (.plt) · GitHub

Author: Philippe Miron

Tecplot library to read binary files created with TECIO or from the Tecplot 360 interface. It is based on the information provided in the "Data Format Guide" available at ftp://ftp.tecplot.com/pub/doc/tecplot/360/dataformat.pdf.

This is based on the #!TDV112 version format. This library is not error-proof, and I have only tested this code using a handful of data files that I use regularly.

git clone https://github.com/philippemiron/tecplot-binary-read.git
cd tecplot-binary-read/
make
./main.bin examples/x.plt

This will print on the console the complete_information() of the plt file.

The printed information makes it easy to see the variable tables and names available, the number of zones, etc.

1. Retrieving the variable name(s):

• vector<string> vars_name = tpobj->getVariableNames();
• string var1 = tpobj->getVariableName(0);

2. Retrieving the number of points or elements in the first zone:

• int number_points = tpobj->getZone(0)->getNumberPoints();
• int number_elements = tpobj->getZone(0)->getNumberElements();

3. Retrieving the variables in the data section:

• if the datatype is float, the following would retrieve data from the first variable of the first zone: vector<float> var1_zone1 = tpobj->getZone(0)->getDataFloat(0);
• Or you can retrieve all the values of all variables of the first zone: vector<vector<float>> vars_zone1 = tpobj->getZone(0)->getDataFloat();

All variables read by the library are available through the getter methods. Take a look at the header file.
