Hello,

I would like to generate a Schlieren-like plot on tecplot. A sample plot that I want to reproduce is attached. I already have the density gradient magnitude from the CFD solver.

A shadowgraph method is explained in this video:
https://www.tecplot.com/2014/10/27/s...ity-gradients/
However, you will see that the plot in the video is quite different than the attached plot. I would like to have only black and white.

Could anyone describe a procedure to produce this kind of plot on tecplot?

Cheers
