Particles have their own volume, so we can't use "Slice" to divide the section, it is difficult to obtain enough interpolation points on a certain section at a certain time. Therefore, I use a "cube area" with smaller width to replace the section. The specific way is to select "Clip" twice to obtain a "cube area" after activating "Glyph".

The above is my solution. If there is a better way, please put forward it in time.😄

In Paraview use a glyph filter, use a vector representation of the velocity

Kind regards

I have implemented this operation. Thanks for your reply!😄

Best regards!

No worries, happy to be of help! Perhaps you could share a screenshot of how you did it so others can see too and benefit from you 😀?

Kind regards

No problem. I will sort out the operation steps and upload them these days.

Best regards!

I sorted out the methods to obtain the velocity vector diagram:

For 2D calculation results：These are the key steps. In order to achieve different expected results, minor changes are required.

For 3D calculation results：Particles have their own volume, so we can't use "Slice" to divide the section, it is difficult to obtain enough interpolation points on a certain section at a certain time. Therefore, I use a "cube area" with smaller width to replace the section. The specific way is to select "Clip" twice to obtain a "cube area" after activating "Glyph".

Great job Jiaming! Thank you for sharing :)

Glad to help！
