Dear Stanisław, Thank you for your suggestion. It works! Best, Zhen On Wed, May 15, 2019 at 4:47 PM Stanisław Gepner <sgepner@meil.pw.edu.pl> wrote:
Hi, to get stream tracers or paths or anything of the sort in ParaView your data needs to be a Vector. You now have separate u,v,w Scalars in the ParaView.
Use the calculator filter and do: u*ihat+v*jhat+w*khat Than apply stream tracers to the Calculator filter node
Pozdrawiam, Stanisław Gepner

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,
Zhen
