 With python, matlab or a simple *awk* command it is easy to put the data in the correct format for the SU2 inlet profile. The awk command below reads the file *inlet.csv*, it assumes that the comma acts as a separator, it skips the first line (the header), and then prints the necessary columns and outputs it in the file inlet_test. We want symmetric data in the y-axis, so we check if the y-coordinate in column 2 is positive, and then we write this data for positive and negative y-coordinates. We write the data into the file *inlet_test*.
