Dear Aidyn, Thank you for your suggestion. It works! Best, Zhen On Wed, May 15, 2019 at 4:44 PM Aidyn Aitzhan <aidyn.b.aitzhan@gmail.com> wrote:
Hello Zhen,
Nektar++ outputs velocity as a scalar components. However, paraview draws stream traces from a vector. You need to concerts scalar components to vector within paraview. Use a calculator to create the velocity vector: u*iHat + v*jHat + w*kHat.
And then use this vector to draw stream traces.

Dear all,
I use nektar++ to do a simulation and visualize the result in Paraview. The simulation domain is a 3D cylinder and it computes velocity in three directions(x,y,z-axis) and pressure of blood flow.
However, I can't use stream tracer filter in Paraview. I read the tutorial of Paraview and can successfully use stream tracer on data inside Paraview. Do I need to compute something else to enable the function stream tracer filter of Paraview? Is there any suggestion？
Many thanks!
Best,
