help contour 2D
 
Hi,
I'm new here and I'm also new as a tecplot 360 user.
I have a file .dat with 3 columns of numbers, thickness as function of two other indipendent variables. I have loaded the data file as a General text and I have plotted the 3D view but now I need to view the 2D contour plot and I don't understand how do that. Everything I have tried give to me the same results ... a white graphic with only the right axes .. :(
thanks for your help

help contour 2d -- "connect" the data
 
Tecplot is unable to create a contour plot from data that is "unconnected" (which is what your data are). One can connect data in Tecplot a variety of ways. Once Tecplot understands the connectivity of the data, then it will be able to produce the contour.

Option 1. -- If the data are 2D one can triangulate via a method described in this tutorial video: http://www.youtube.com/watch?v=3FMTLQ-ozKA

Option 2. -- If the data are on a regular XY grid, one can create a grid in Tecplot Data>>Create Zone>>Rectangular and then interpolate the data onto the newly created grid Data>>Interpolate


Cheers,
Scott

Thank you very much!! Now I can see the contour of my data. :o

Hello,

my problem is as follows:
i have data velocity magnitudes in an excel table. Each cell has a coordinate (x,,y) which is associated with the location in space where the velocity was measured. v=f(x,y). How do I import the data correctly?

Until now i had no success. I have imported the data from excel (table size 21*31) gotten 21 variables in tecplot. Crated rectangular zone and interpolated.
Unfortunately i can only plot contour where my x and y axes are one of those 21 velocities columns and can choose a third one to do the colouring with.

thank you very much.
