Evenly Spaced Streamlines 2D

This seems right. Also make sure the seed point is in the same plane normal on Z.

If that does not work can you share you dataset?

Thanks,
Dan

Dear Dan,
I am in a similar situation to that of Nayla.
I have a 3D data set and I follow the path:

calculate 2D vector using U_XiHat+U_YjHat
take a 2D slice normal to z
try to use the filter and he tells me I am not on a XY plane.

Can you please give me a suggestion that might point me in the right direction?
Thanks a lot.

Joao

3D data

Dear Dan,
Please see the downloadable data.
Thanks a lot.

Best wishes,

Joao

It seems that
2D_data_test/2D_data_test_0_0.vtu

is missing from the zip archive.

Can you check this?

Thanks,

Dan

Dear Dan, sorry.
That file should not be required for the problem at hand.
Basically I took a slice, used the calculator filter to get a 2D vector with U_XiHat+U_YjHat and wrote it as a vtk file. Then I tried to open it and do the 2D streamlines but it did not work.
Please see in annex the file. 2D_data_test_0_0.vtm (637 Bytes)

please provide 2D_data_test/2D_data_test_0_0.vtu

Can this be of use?
Thanks a lot

I think you are looking for the data Joao has provided here. I tested the evenlySpaced filter in this case many times with no success. As it is an OpenFOAM case, you only need to open “foam.foam” from within paraview.
