[Paraview] Fwd: Re: how to resample data onto a new grid?

[Cook, Rich]

Thanks for cc'ing me.  Piece Invariant does not fix the problem.  I thought it would too but it does not
Thanks!

I sent my reply to the paraview list but just noticed that you weren't cc'ed on it so I'm resending it again to you privately in case you aren't checking the list.

Regards,

The main issue starts with the fact that for multiple processes that when you use the cell data to point data you're not getting a continuous value across processes. The cell data to point data filter has an "Piece Invariant" option which you should check so that it uses ghost cells to compute the point data and thus you should get continuous point data values between processes. Then the contour should work as you want it to.

Hi!

Try ResampleWithDataset filter. Its input is your data and mesh on which
you want to resample your data.

Hi,
I have a dataset that shows cracks when I make an isosurface, because it's in multiple domains and paraview doesn't know how to do ghost zones with it.
In VisIt, I can solve this by resampling onto a grid which is the same size as my input object.  This new grid gets the proper ghost zones and solves the problem.
In ParaView, can I do the same thing?  Here is a picture of what I'm talking about.  You can see the cracks where the processor data boundaries are; one per processor.  This is a fault with the data reader (which I maintain), but I'm hoping I can solve it with the GUI.
