Hi everyone,
i am currently not sure if its a bug in paraview or i screw up something with the creation of the .vtu
I have got a vtu that contains cell data.
first_run.5.000001.vtu (6.0 KB)
But they are not showing up in the find data panel.
while paraview clearly recognizes that there is some cell data
This worked at least a year ago when i first wrote my code to create those vtu. And i haven’t touched that code part since then.
Could someone please help me here.
tl;dr
Select cells instead of points.
I’m guessing the problem is that you are doing a selection on point elements and then trying to view the cells. In this case, ParaView is doing something weird. It is extracting the points making a fake “Vertex” cell around it, and populating the spreadsheet with that. Because the selection is (potentially) a partial cell, the cell data is not captured.
To see this better, here is an example where I created a simple sphere surface. If I create a selection of cells, you see that the spreadsheet shows the cell data just fine.
However, if I do a selection of points, you can see that ParaView is extracting some “Vertex” type cells that do not exist in the real data and no cell data shows up.
What makes this very confusing for your data is that you started with Vertex cells. It looks like ParaView is selecting your cells, but it is not. Granted, ParaView could have a special case for single Vertex cells, but it doesn’t.
Although I understand this behavior, I rather wish ParaView instead showed cells incident on the selected points if for no other reason that showing a collection of fake cells with no data is pretty useless. At any rate, this has been the behavior for at least since ParaView 5.10. Maybe there is a technical reason for this behavior.
@Kenneth_Moreland you are the best! Absolutely right!
It was indeed the wrong way of selection.
