[Paraview] Help Need in Streamline for CGNS file

[Richard GRENON]

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.
