Hello.
For streamlines on a curved surface, you should get better results using
the SurfaceLIC plugin.
First, you have to load this plugin through the menu "Tools->Manage
plugins": select the SurfaceLic plugin, then click on the "Load
selected" button. You can also click on the little cross before
SurfaceLIC and check the "AutoLoad" check box: thus, the plugin will be
loaded each time you start Paraview.
Then, you should have a velocity Vector in your dataset. If you have
not, build a vector from three scalar components using the Calculator
filter.
When you have a vector data, the "Surface LIc" item is available in the
list of representation mode. Select it and you will get a picture that
looks like an oil flow visualization. You can adjust some LIC parameters
in bottom of the Display tab. You can choose another vector if you want
because LIC uses by default the first vector that it finds, and it may
be the normal vector.
