[Paraview] Extracting data on the surface of a block?

[Utkarsh Ayachit]

Loius,

Looks like what you have is quite reasonable. You can drop the
"Extract Surface" filter and simply connect the "Plot On Intersection
Curves" to the "Merge Blocks" as the "Plot On .." filter does an
"Extract Surface" internally.

Another option, if you want finer control over the sampling resolution
would be to use the "Resample With Dataset" filter" with a custom
source that correponds to the sampling locations. I created one by
using a Sphere source and then slicing it. State attached. By changing
the resolution of the Sphere, you can change the refinement.

Hope that helps

Utkarsh
