Header for ASCII file
 

Hi, Dear all.
i simulated vortex shedding behind a circle with ANSYS-Fluent 15 and for some post-process i export an ASCII file and edited this file with MATLAB.
now i want to plot this ASCII file in tecplot and i have problem with the header file. this is my geometry:

P.S: i export data of a channel without an obstacle in ASCII file and use this header:
VARIABLES="X" "Y" "U"
Zone I= 201 J= 101
and worked correctly. but when i use a similar header for channel with obstacle it doesn't work corectly.

can anyone help me?
excuse me for my bad English.:o
thanks in advance.
