Help required regarding boundary conditions


#1

Hello! I am new to CFD and am working on this project https://www.simscale.com/projects/MS9991/hoop_glider/
The conditions are that this object is thrown at 5m/s velocity in air. I need to visualize the flow lines resulting the flight of the object. What boundary conditions should I use>
Thanks!

Hi there!

Go to the post-processor and go to “Particle Traces”, then to “Seeds” and choose the option “Pick” at the very bottom to choose the source of your streamlines.


Additionally I think that your flow region is too small and that the boundaries will have a strong influence on your flow behaviour. I would fix it and see how the flow quantities change.

Hope that helps!

Thanks for the help!
Eager to see how things change after you fix it!
