Re: [Paraview] Down sample data?
You could try the Append Attributes filter instead of the programmable filter if the geometry is the same for both/all inputs into the Append Attributes filter. To use the Append Attributes filter just select the filters in the Pipeline Browser that you want to compare. Note that for 5.4.1 and earlier you'll need to use something like the Calculator filter to rename the arrays while for the 5.5 release candidate it will do automatic renaming for you.

Re: [Paraview] Down sample data?
Andy, I found that the "plot over line" filter will allow me to do sampling. However, that has lead me into a second problem. So I feed 2 "plot over line" filters into a "programmable" filter (to take the difference between the two datasets). I then integrate the difference over space using the "integrate variable" filter. Then to extract all the time step values, I try to use the "plot selection over time" filter; however, Paraview crashes when I try to apply the "plot selection over time" filter. Any advice?

Re: [Paraview] Down sample data?
Hi John, It depends on what type of grid you have. For image data, rectilinear grid or structured grid the extract subset filter is probably the best (for other grid types it will be grayed out since it's not applicable to those grid types). Otherwise, you can use resample with dataset. Note that both of these will work nicely with point data but for cell data you may want to use the cell data to point data filter first.

[Paraview] Down sample data?
Hello all, I'm trying to down select my data so I can do a grid convergence study. How would I go about doing this? I found an old post ( https://public.kitware.com/pipermail/paraview/2010-November/019453.html) that recomended doing an "extract subset" filter; however that filter is grayed out.
