[Paraview] Using data in Calculator from multiple sources

[Bastil2001 at yahoo.de]

Matt,

do you have a correspondence between the nodes meaning node1(x) of
model1 needs to be compared with node1(x) of model2? Otherwise this will
not work and you have to search for nearest nodes first.

Regards Basti
