Ijk ordered data
 

Hi all,
I am new to tecplot and now try to test the 3D visualization capacity. I wonder if someone can help explain how to determine imax, jmax, and kmax for the I j k ordered data. When I play around with the below data set and found that changing "I=3, J=4, K=3" to "I=4, J=3, K=3" will change the shape of the 3D contour, so would like to know the physical means of these values.

Thanks,
John
