[Paraview] [EXTERNAL] Re: temporal threshold

[Moreland, Kenneth]

Actually, I wrote Temporal Statistics filter. David T. co-wrote the descriptive statistics and host of other statistics filters that I believe operate on a single time slice. I also believe they all work in parallel except there is an issue with replicated points in parallel data that has never been resolved.

You may be right.  I am just dredging up old memories from a few years ago.  David Thompson should remember - he helped write the filter.  David?

It doesn't? I thought it worked in parallel but didn't work if the topology changed.

Dave,
Not related to Tim's issue below, but - if I remember correctly - the temporal statistics filter does not work in parallel.

Strange, when choosing the defaults on the Temporal Statistics filter the output should be a copy of the input with each attribute array replaced with name_stddev, name_average, name_maximum, and name_minimum arrays.

Try it on the Source->Time Source to see how it should behave.

Thanks, I've run the temporal statistics filter on my data, however it doesn't seem to be giving any data output.  It spends a while calculating, but the output is just a solid color representation of my object. The information tab also shows no data.
My input is an unstructured grid, with point data. Am I missing something?

the temporal statistics filter will show you the max/min/avg etc over all time. Threshold that to identify the nodes of interest.

I'm trying to apply a threshold to a temporal data set. I would like to see which nodes reach a certain temperaturetry  over the whole simulation. At the moment the threshold will only see one moment in time.

Maybe there a way to apply a temporal threshold? Such that the filter will apply the scalar value for all timesteps?
