tecplot doesnt recongise grid boundary in external flow

% var_name: the name of the variables, is a cellįunction = tecplot2mat_3D(filename) % var: the data of variables, is a four dimensions array, the last dimension is the the number of variable % filename: the name of the tecplot file including the extensions % read data from tecplot file, and save the variables to mat Usually the first three data are x, y, z, corresponding to the grid point spatial position. The order of the data in a row corresponds to the order of variables defined in the second line of the file header. By processing the second line of text, you can get the defined variables and their number.Ī row of data in a tecplot file is a record. The first three lines of the tecplot data file are the file header, the first line is the data file description, the second line is the variable name defined in the file, and the third line is the flow field of the Cartesian grid, which contains each The number of discrete data in the spatial direction.

Then for a tecplot Data files, matlab cannot be read directly, there must be a function to convert the data in the tecplot data file into a data format that is easy to operate by matlab. However, it is more convenient to import the data into matlab when processing the data. Based on the Cartesian grid-based three-dimensional flow numerical simulation, the flow field information can be output in tecplot format, which is convenient for tecplot to visualize the flow field.
