Hello All,
In the Extract Block Filter while selecting an extra face (ie..Ground) the display is culing the whole Geom.
PV version 5.12

That’s curious. How large is the mesh. One thought is that the ground plane is so large that it may be overwhelming your GPU RAM and the previously shown geometry is being culled.
Any chance you can share the dataset?

This is a OOTB demo example from OpenFoam (incompressible\>simpleFoam\>windAroundBuildings).
The mesh extent and data are as follows

I’ve stripped the solution and zipped as 7z , the issue.pvsm should replicate the issue as\_is on pv\_5.12.

@cory.quammen curious if got a chance to review /any luck with dataset provided ?

The archive seems to be missing the `para.foam` file referenced in the state file.

i can open the \*.pvsm without the para.foam

para.foam is a placeholder .. can you create one using ( touch para.foam)

Got it - I’m able to reproduce what you see in ParaView 6.1.1.

This is a small dataset with 215k cells, so that’s definitely not the case.
I’m seeing a lot of duplicated geometry in the “buildings” block when the “ground” and “buildings” blocks are extracted - something might be wrong in the **Extract Block** code.
It’s also inconsistent. If I extract “ground” and “buildings”, I see the problem. But if I add “inlet”, hit Apply, then, remove “inlet”, the “ground” and “buildings” geometries appear correct.
I checked back to ParaView 5.9.1 on macOS and this problem exists in it, too.
I filed an issue here: [https://gitlab.kitware.com/paraview/paraview/-/work\_items/23320](https://gitlab.kitware.com/paraview/paraview/-/work_items/23320)

Thanks @cory.quammen for looking into the issue ++replicating the behavior 👍 .
one additional thing to also notice is that this issue recurs when the internalMesh(coreMesh), in addition to the other faces, is chosen in ExtractBlock- just mentioning -in case this helps to drill down the unusual suspect!
