Secondary Flow/Vortex Analysis in Streamcut Plane

CFDVoyager

Hello All,  I am analyzing secondary flows in a streamcut plane and came across a paper that  looked into this however it does not adequately describe a plot(fig attached). The color contour in the paper is relative Mach number, but there are

also contour line-like structures with directions. What do these represent and how do I plot those? Are these q-criterion/lambda-criterion?

    Hi, thanks for getting back. Yes this indeed looks like what I want. Yes I am also doing Wxyz and surface type but I am still gettting straighter lines as shown in the figure I listed before. When plotting vector lines, are you using 'Vector lines from section' option? Can you please briefly list the steps and settings you used?. Maybe if you could do one for a common case like 'rotor37 tutorial case' that would be great so I can try to replicate.

    Here are the steps:

    - Select the cutting plane of interest (right-click on the plane in the list -> Select)

    - Select Wxyz in the list of quantities

    - Go to the "vector lines parameters" window and select "mode=surface", "direction=both"

    - Select vector lines from section

    - left-click somewhere on your cutting plane and drag the cursor somewhere else on the cutting plane. By default, it will seed 5 streamlines between the two selected points. You can repeat a couple of times to add enough streamlines on your plane. 

    If you are still having issues, please contact our customer's support directly and we will troubleshoot on your specific case. Thanks!

    Awesome! Thanks. I will try this and if not will contact support.
