[Paraview] Surface LIC Problem

[Magician]

Hi all,


I'm trying the Surface LIC Plugin.
My models are formatted as VTK MultiBlock Dataset, and there are geometries
of fluids and walls.
I'd like to visualize LIC on the walls.

First I applied Surface LIC to the walls, the results are something wrong.
Next to the fluids, they are OK.
But there are extra walls which I don't want to visualize (ex. Inlets/Outlets, external boundaries).
Maybe the reason of the walls are that they don't have the velocity values of main flows.

I also tried the Resample with Dataset filter for linking main flows to the walls.
The results are roughly good, but sometimes the resampling qualitys are poor (dropping the values).


Is there a good way to visualize the part of the walls' LIC?
My sources have complicated shapes, so I want to make the best use of the information of blocks of walls.
