[Paraview] Fluid Flow Simulation in ParaView

[Rohit Narurkar]

Hello!

I tried applying the "Glyph" filter, but still the negative values aren't
being considered. It considers only the magnitude.

Can somebody please explain in detail how I should go about this? Please
have a look at the .vtk file I have attached above, I am stuck at this
point.

Thank you
