[ParaView Postprocessing 12] Fluid flow: stream lines

In this video, we continue our work on visualizing fields, but this time we use another technique: stream lines, which are one the best ways to see how fluid flow fields behave. Let’s do that for our degrading object inside the flow field.
Codes and Resources:
In order to follow the videos and reproduce the output, you need the raw simulation results. You can find these files here: tuxriders.com/v...
Topics covered:
🎯 Using stream tracer filter
🎯 Working with camera settings to precisely adjust coordinates
🎯 Combining the stream tracer filter with a tube filter
🎯 Changing background color
Lecturer: Mojtaba Barzegari mbarzegary.git...

Thank you so much! It's very clear and easy to understand

[@TuxRiders]

Glad to hear that :)

[@hughtong5551]

Amazing tutorials! Thank you!

[@TuxRiders]

Glad you like them :)

[@sikandaryosufzai2790]

very nice tutorial, can you make a video how to show the colume of water passing over an object? or maybe you can write the proccesses here under comments. tnx again

[@TuxRiders]

you're welcome. actually what you are saying seems to be a simulation rather than a postprocessing, so you first need to model the physics in any desired tool and then visualize it in ParaView.

[@范博伦]

Do you know how to have streamlines which are seeded from the inlet and terminated at the outlet in order to get the integration time as the fluid parcels' residence time?

[@TuxRiders]

I'm afraid I don't. Sorry.

[@范博伦]

Thanks for your reply.

[@ivanzaev7538]

Can I save the stream lines over trajectory with plotted variable, say Temperature

[@TuxRiders]

it should be possible, but I have never done that unfortunately, so I don't really know how to do it. sorry.

[@刘雨纯]

May I export the stream lines out with colour?

[@刘雨纯]

I find a way to export it! (add tube then export it) Thank you!

[@TuxRiders]

it's good to know that you solved the problem :)
