[Paraview] csv -> vector variable -> streamline problem

[James Furness]

Hi,

I have a csv file that is a 16x16x16 of data in the form: 

x, y, z, rho, j_x, j_y, j_z

I am using a pipeline of:

csv Reader  |  Table To Points (x, as X Column… etc.)   |  Calculator (iHat* j_x+jHat* j_y+kHat* j_z)   >    Result

Looking at Result in the spreadsheet view shows a vector variable as I would expect. Also, visualising the result of the calculator filter as 3D Glyphs displays an expected grid of arrows, but they are all oriented pointing along the X axis. When I colour this by the Magnitude of Result they are coloured as expected, with the expected areas of high magnitude being red etc. 

I suspect I have already run into problems at this point, but if I continue and add a Stream Tracer to Result I see nothing. There are no streamlines shown.

I have been trying to work out the problem, and been searching around for any clues. Any help on pointing out where I have gone wrong is greatly appreciated.

I have attached the example csv.

Many thanks,
James
