Hi
this is my first post ever on a forum, sorry in advanced if i did somthing wrong.

I'm a bachelor student currently working on my theses, im supposed to examine the effects around a annular ving. I have run a modell in a vindtunnel, but the tunnel cannot use smoke. and i need to visualize the flow around the model in star-ccm+.

i have some issues when i try to visualize the vingtip vortecies, i get a good swirl the first 2-3 chord lenghts behind the airfoil, before its completly damped and sreamlined. i tried to add the physics model "vorticity confinement model" and use it according to the user manual, but cannot get a visualization.

the test are run at conditions simular to sealevel , and speed range 10 m/s - 45 m/s

i would realy love som tips on good techniques to visualize the flow.

Thanks for your time.
