[Paraview] Colormap cut planes and contour filter in an unstructured grid

[Andrew]

Hello.
For planes, use the Slice filter. Check the "Crinkle slice" option if you
want to see exact mesh elements. For vector components, select vector and
desired component in top toolbar of ParaView window. Then set scale with
Rescale to custom data range (find this button in the same toolbar).
For isovolumes I use the Threshold filter (it's fast and the volume's
surface is what we need if we just want an isosurface). I recommend to make
the result transparent in some extent to represent the volume better. To
make vector components accessible with the Threshold filter, use Edit -
Settings - Auto Convert Properties (under Data Processing Options section).
As an alternative, you can create the component scalar with the Calculator
filter.
