Hi all,
I have issues with using the ProcessIdScalars filter with the GhostCellsGenerator for a Uniform Rectilinear Grid.
I first open this data (3.4 KB) that I produced in built in mode using the Wavelet and the GenerateGlobalIds filters.
Here is my pipeline, that I execute using MPI with pvserver:
volume_global_ids > ProcessIdScalars > GhostCellsGenerator
All options are at their default values.
Now, if I open the Spreadsheet View and look at the point of Global Id 35 (line 112 to 115) in the screenshot below), I can see that it is shown on 4 processes, and for 3 processes it appears as a ghost point (which is what it is supposed to do).
However, the ProcessId values are not correct: they should all be equal to 2, as it is the only process on which the point is not a ghost, but on processes 0 and 4, the value of ProcessId is 0.
Could this be related to the fact that vti files are automatically distributed and duplicated some points on the border? In my example, the point 35 is indeed duplicated on both process 0 and process 2, before calling any other filter.
Many thanks
