[Paraview] [EXTERNAL] Re: Selecting a point in Python

[Scott, W Alan]

Excellent!  Thanks.

One more question – is it possible to select the cell or point with a maximum value, as opposed to a hard coded cell or point?

HI Alan,

Selections are indeed possible in Python, though as you have found they are not recorded in traces.

You should be able to do something like this to select one or more points:

can = GetActiveSource()

# Extract the desired block first

extractBlock = ExtractBlock(Input=can)

extractBlock.BlockIndices = [2]



# Now extract point 1764
pointID = 1764
pointIDs = [0, pointID] # process number, point ID
selection = paraview.simple.IDSelectionSource(ContainingCells=0, FieldType = "POINT", IDs = pointIDs)
plotSelectionOverTime1 = PlotSelectionOverTime(Input=can,
    Selection=selection)

qcv = CreateView('QuartileChartView')

d = Show(plotSelectionOverTime1, qcv)


I hope this helps,
Cory

I am trying to create a python script that will create a plot selection over time.  Here is what I am trying to do:

•         Read in the can.exo.  All vars on.  Apply

•         Select point on can. (This is the line that does not record in the Trace Recorder, and I need).

•         Plot selection over time (I can’t get here without the previous step).

How is a selection done in Python?

Thanks,

Alan
