Default Unstructured data with Tecplot
Posts: n/a
Hi everybody!

I've been wondering if there is a way to visualize completely unstructured raw data with Tecplot.

I have 2D data points, and for each point 6 variables. I don't have any connectivity information, and the points are not ordered in any way.

the file I am working with looks like that:

<x1> <y1> <velocityX1> <velocityY1> <pressure1> <temperature1> <x2> <y2> <velocityX2> <velocityY2> <pressure2> <temperature2> ..... and so on ....

In Gnuplot this is very easy to realize. just plot the file using the columns you want... But I need to do it in Tecplot.

I hope I am using the right forum. Thanks in advance!

oops, I just saw that my file structure didn't work. let's give it another try:

x1 y1 velocityX1 velocityY1 pressure1 temperature1 x2 y2 velocityX2 velocityY2 pressure2 temperature2 ... xN yN velocityXN velocityYN pressureN temperatureN

this is how my file looks like

yes you could, basically you need to write a program that will arrange your file in Tecplot format ( a C/C++ or FORTRAN code ... ).

If you really need a code like this contact me,

Hey Paul,

thanks for your reply. In the meantime I already wrote a program like that.

It is a little strange because I create the connectivity information artificially where it has never been. But it's fine. I just switch off the mesh in Tecplot, and it's alright.
