[Paraview] Resampling to a uniform grid

[Moreland, Kenneth]

Note that this will only work when running in serial. I'm sure that in parallel this will not sample correctly. That would require communication to resolve uneven distributions in the unstructured grid. I don't think anyone has written something like that yet.

You could start with Sources->Wavelet and reposition it as needed, but I'ld use a python programmable source. Attached is a state file to demonstrate.

Folks,

I would like to resample a scalar field defined on an unstructured
grid in 3D onto a uniform rectangular 3D grid with specified logical and
physical dimensions.

It seems from the ParaView filters documentation that this can
somehow be done using the Resample With Dataset filter. It appears
to me that the procedure involves generating a uniform rectangular
grid in some fashion and then feeding it to the Resample With Dataset
filter along with the unstructured grid containing the scalar to be
resampled.

However, I am confused about just how to make the rectangular grid of
specified size in the first place and about how to use it with the Resample With Dataset
filter.

Could someone explain to me how to do this ?

Thanks,

                                       --Bob
