Summary0011637: Particles don't show up multi file
DescriptionI have a dataset that has particles show up when you open one file, but not multiple files. This dataset read correctly in PV 3.6.2, but has not worked since then.

To see what it should look like:
* ParaView local server, Linux client (anything will do), trunk.
* Open particles.exo. All variables on. In blocks, turn on ParticleBlock ONLY. Apply.
* Filters/ Warp By Vector. Take defaults (Coords_, and 1). Apply.
* You should see lots of points.
(As a cool simulation, turn Sets surface_4 on. then, color the points by Radius.)

To see the problem, open dataset paralan.e-s0003-2.[0-1]. This is just the datset above, plus another one. Repeat directions above, notice that you don't see anything.

Also, compare the Information tab from both readers (single file and multiple file). With single, you have the same number of points as cells, with two files, you have lots of cells but one point.

If possible, this is very high priority for 3.10.0 (but not a show stopper.)

Ask me for the file (data/alex.../particles tar file)

 The issue was the vtkAppendFilter default behaviour was changed to merge duplicate points, this has been fixed in VTK since this behaviour was not correct.

When merging a multiblock to a u-grid, we want to merge duplicate points.

Now that vtkAppendFilter doesn't merge points by default, we need to turn on the ability to merge points so that the resulting u-grid has no duplicate points.

 Excellent, Robert gets a pat on the back. It looks great.

Tested local server, windows, trunk.
