Tecplot data file

The Tecplot data file format is constructed for making plots with the Tecplot software. It consists of a three-line file head, which includes the variable descriptions and the definition of the 2-D grid structure. The Tecplot data matrix has 11 columns. Every row of the vector map data is for one evaluation point. The first five columns of the vector map are position and displacement vector components in pixels, whereas the last five columns are position and velocity components in mm and m/s. The center column is the validation flag. The extension name of the data file is “.dat”. The Tecplot data file may contain maximal three zones for M0, M1 and M2 respectively. Following is an example of the Tecplot data files.
