Summary0004652: SNL: Data Analysis filter, client/server and line bad
DescriptionI am trying to get the Data Analysis filter to work in line mode when running client server. It doesn't.

Linux
ParaView 2.6.0
Run ParaView client server, open with a few processors.
Open can.exo
Turn on all nodes and cells.
Turn off compositing.

Add a Data Analysis filter.
Query method: line

Default location of the line should intersect cells, so leave it alone.

No scalars show up to enable, and if you hit Accept, it just says that it doesn't have anything to plot.

I spent some time this afternoon looking into this. The problem is that the default location of the line passes through the narrowest part of the can.exo dataset. When the probe filter (used internally by the data analysis filter) walks along the line looking for the closest point in the dataset to each point in the line, all of the dataset's points are too far away from the points on the line, so the probe filter says that no points are close enough, and so no attribute data is added to the line.

This filter works fine for other datasets where the line passes through more of the dataset, so I think I would classify this as user error rather than a bug in ParaView.
