I have a structured grid, but in unstructured file format(.vtu).
It can be converted to structured format (.vts), but there are some reasons I want it to stay in unstructured form.
But I still want to use structured ijk coordinates.The grid has id values, which can be easily converted into structured ijk coordinates.
So I used calculator to add to Cell Data scalar i, j, k values, so it allows me to use “iso Volume” to slice over them. but “extract subset” does not work.
Is here any better way to add ijk indexes to unstructured grid?
I work with petroleum reservoir models, they are structured, so I can actually use vts, but some times they may have faults (offset between neighboring cells) (PictureOfFault)
So the main reason are faults,
The second reason is that “Extract Selection” does not work properly on structured models. (Of course I can use other options like “Extract Subset” for these reasons, so, it is not the main reason, but still for extraction “Extract Selection” is much more convenient), I still need “Extract Subset” for visualization of different layers.
