I am starting using Paraview beyond simply plotting vector glyphs, and have some questions about which filter, or stack of filters fit my needs when making particular output.

As a source:
I have a data-set with vector E-field evolution in time, where the mesh grid is fixed in time.
And technically I can acquire H-field data, but it is not there initially.

1) not important any more

2)
- Phase of Ez component of the vector (E-field vectors rotate according to elliptic polarization, linear polarization is a particular case)
And plot equiphase surfaces with contour. Any visually correct approach would fit. I can try calculating Poynting vector (see question 3), for simply making "asin(Norm*|Ez|/|S|)", if there's no way of extracting the phase from the vector motion.

So, I don't know how to extract Magnitude of the vector and a Phase

3)
If possible, I want to plot a Cross-product of the E-vector with specified direction vector (manually defined, or H-field).
Technically, I want to compute a Poynting vector field, in order to locate the focal sources of the field.

4)
Instead of equipotential contours, I would love plotting semitransparrent mist/clouds, depending on the magnitude of the field.
Is it possible?

Thank you for any help on any of these points.
