I am using KIVA for my CFD analysis. I was unable to open the the results of the post processing files in tecplot even though they are written to be redeable in tecplot. What could the possible reason be? Can anyone help me?

If your results have the tecplot format, you should be able to open them selecting: file - Load Data Files - search the name of the data file.dat

Thanks Oscar, but I think the the results are not in tecplot format. So can you please tell me what format tecplot uses.

Ok.- Here is the format I implemented in my programs for the tecplot output:

TITLE="here the title" VARIABLES= "x" "y" "z" "U [m/s]" "V [m/s]" "etc" ZONE N=7974 E=24000 F=FEPOINT ET=TETRAHEDRON T="time=1" x-coord y-coord z-coord u v etc inmediately next to this columns you have to specify the vertex-number of the tetrahedron where you're gonna interpolate.
