Hi Cory, I'm stuck with this issue :(
1. Changing just the pvti file is not enough: I got a segfault using the raw binary files. 2. I tried also adding a dummy slice at the end of all pieces to fix the problem that I reported in one of my previous emails. So, instead of changing the PVTI files I tried changing the VTI files. 2.1. First of all, I had to increase the number of tuples of the VtkArray because I was adding the dummy slice. Since I didn't change the whole extent and the piece extent of each VTI file, I got this warning message:
Warning: In /opt/VTK-6.2.0/Common/DataModel/vtkDataSet.cxx, line 421
vtkImageData (0x3450390): Point array Var with 1 components, has
4080501 tuples but there are only 4040100 points
This didn't work either.
2.2. Afterwards, I tried modifying also the whole extent and the
piece extent. This seemed to work :)
Despite 2.2 seemed to work, I'm not sure if this is a valid solution or just a workaround: If I open a VTI file directly (because I want to see the data produced by a MPI process) the dummy slice is visualized.
From my point of view, I think that we're trying to address an issue of the PVTI format modifying something that works fine (VTI files).

Cory,I did not change the VTI files in the first experiment but it crashed anyway.Thanks!

I tried to different things without regenerating the *.vti *.pvti (using the zipped raw version): 1. Changing the piece extent in all the *.pvti files to what you proposed in your last email -> segfault 2. Changes describe in 1. + changing the whole extension of the VTI files that contain the second piece -> Paraview warns me because the size of the second piece doesn't correspond with the data. vtkXMLImageDataReader (0x419ef70): Cannot read point data array "var" from PointData in piece 0. The data array in the element may be too short. Following your advice, I will try to generate an extra dummy slice in the first piece. I will let you know the results :) Best, Sergi On 08/11/2015 11:57 PM, Cory Quammen wrote:Actually, you could try one other thing first: Change the extents of the pieces in the .pvti files to the following: <Piece Extent="0 200 0 200 0 100" Source="ascii_2_0.vti"/> <Piece Extent="0 200 0 200 100 200" Source="ascii_2_1.vti"/> I'm able to load the files and move between time steps fine doing this.

When you load it, the valid values from the first piece will overwrite the dummy values. I'm frankly surprised this extra slice would be needed because the ghost level is set to 0. But I'll admit I don't fully understand this format yet.

Should both pieces contain this slice? In my case, each MPI process computes something and writes its portion of the mesh. All these portions are completely disjoint among them. Thanks!
