[Paraview] Placing a ContourPlot under a Plot3D

[Emna Reseach]

Hi

I would like to combine a 3-dimensional graph of a function with its
2-dimensional contour-plot underneath it in a professional way.
 But I have no idea how to start. My computations are done with the help of
freefem.

Does anyone know, if it is possible, how to do this?
 Thank you in advance.
