Hi when i run my vtu file on paraview stream tracer is greyed out. I created my file on Freefem. İ need to great stream lines on a slice of 3d velocity . How can I do?
please share your data
u.vtu (108.0 KB)
Your data does not contain any vectors
How can I add ?
Not sure what you mean. You have u
, scalars1
and scalars2
, do you want to create a 3D vector fromt them ?
Yes. İ obtained this data from freefem as solution 3d velocity. İ need to get its streamlines but i don’t know how to add vectors to the data
Thank you I’m going to try.
Hi to get this which filter did you use? İ did merge filter components and select stream tracer. Mine didn’t turn out like this
Please share a screenshot
The first one is after i applied stream tracer.
The second one is after i applied merge vector components
Here is what I did:
- Open ParaView
- File → Open → u.vtu, Apply
- Filters → MergeVectorComponents, XArray = u, YArray = scalars2, ZArray = scalars3, Apply
- Filters → StreamTracer → Apply
İ did the steps. This happened
Also i need to display streamlines generated by line segment source { (0.5,0.5,z) :0<z≤1} how can I do it
Which is good ?
Yours is better. İ want to get like this how can I do it
- Click on the “MergeVectorsComponent” in the pipeline browser
- Show it by clicking the eye
- Set opacity to the representation to 0.2
You may want to read the tutorial though: Self-directed Tutorial — ParaView Documentation 5.11.0 documentation
Well thank it worked. My main aim is too get a vote like the one I attached now. How can I do

İt was said that “display streamlines generated by line segment source { (0.5,0.5,z) :0<z≤1}”
