You can a) Set up the field variables in Analyze --> Field Variables dialog
b)Calculate z-vorticity in Analyze -->Calculate Variables. See attached figure here. (I am using Tecplot 360 2018 R2)

There was a bug with padding for element center data, so the updated code is attached here. mat2tecplot_v1.7.zip

====How to use======

1) unizp the mat2tecplot.zip file to get mat2tecplot.m

2) Open it in MATLAB or Octave,

3) Type in the command line terminal

Hi Engineers,

I'm trying to simulate fluid flow inside Lid-Driven cavity using MATLAB, and I'm using Tecplot 360 v2018.1.1.87425 on win. 10, 64 bit. And I'm facing a problem with streamtraces while plotting the contour lines the streamtraces didn't match with the contours, they appear as straight lines from the lower left hand corner with no physical meaning for that and they should be curved to show the vortexes and eddies at the corners. I'm attaching the image and the dat file

Any help would be appreciated

Thanks in advance

You need to have variables loaded to generate the streamlines. The streamlines are being calculated by X&Y values so they are straight lines. If you include variables to represent U/V vector variables the streamlines should properly.

Thanks novedevon for the quick reply, I included 2 more variables in the dat file and they are the horizontal and vertical components of the velocity (u,v) to be able to plot streamlines properly.

Thanks a ton

I tried to convert measured data as plain line data. I used tdata.lines.x for time and tdata.lines.v for the measured data.


Is it possible, that y and z are not "optional" as said in the documentation?



Can someone help here?
