[Paraview] Transform time to an additional dimension of the grid

[Frederic Perez]

Hi,

I have a 2D regularly-spaced rectangular grid on which node values
vary over time (the grid does not change). Note that this grid has
many many scalar fields at the nodes. Not just one.

I would like to
1) extract only one of the attributes (one scalar field)
2) append all the grids from each timestep together in order to form a 3D grid
3) plot as a usual "volume" or "surface" and apply slices, thresholds, etc.

For now, I have tried to "Group timesteps" (I don't understand what it
does) and "Plot selection over time" (it only provides point-by-point
plotting on line graphs).

Is there a solution?

Cheers
Fred
