RES: [Paraview] Probing a solution position over time

[Renato N. Elias]

Hmmm... Ok

- A point over time will produce a 2D plot with the solution evolution over
time (I did it).

- A line over time should produce a 3D plot with the solution distribution X
line distance X time (and PV can't render a 3D plot yet, ok).

Here is the my problem: With a punctual probing PV will give me the value
animation at that specific point in the space. I was thinking about
specifying a scalar value and get the position variation (coordinates over Z
axis) of this scalar value over time. 

Let me try to make me more clear. I'm doing a free surface simulation and I
would like to track the interface between 2 fluids. The interface is a
scalar value defined by 0.5. Thus, I need "to glue" a point at the interface
(defined by the value 0.5) and see this point position oscillating over time
OR put a line (as it was a scale) in my model and see the value position
over the time

I don't think probing with a line over time works. This is the case because
the built-in plot is 1D and cannot do carpet plots. If you animate that, it
will generate the plot for the current time only. I think you can only probe
with a point over time.
