[Paraview] Plotting velocity vectors

[Utkarsh Ayachit]

You can use the "Calculator" after Table to Points to create a vector
from 3 scalar values using the following expression:

iHat*x_velocity+jHat*y_velocity+kHat*z_velocity

You can also scale the values in the calculator itself to do any unit
conversions needed. Then you can apply the Glyph filter.
