Add Magnitude meta-ppfield

[k]

You gave me what I asked for, but I didn't know what I wanted... Now I think I know. Could you create a PPField for the magnitude such that the plot to screen looks like the picture on page 414 in the FEniCS book?

Do you mean

L2Norm ("Velocity", params)

[k]

Så vidt jeg forstår plotter L2norm en skalar verdi for vært tidssteg. Jeg ønsket meg det samme som du får ved å velge magnitude i paraview evt warp by vector. men det kan vente til mandag ;)

Add a field

Magnitude("Velocity", params)

which returns a scalar field of |u| for any field.
