[Paraview] [EXTERNAL] Re: temporal threshold

[Moreland, Kenneth]

There is no straightforward way of getting around changing topology.

One so-so way to solve the problem is to build a static topology and use the Resample With Dataset filter to apply the field values in the changing topology to the static topology. You should then be able to run the temporal statistics filter on the static topology.

Thanks, I see from Ken's comment that my problem is a changing topology. Some of the nodes in the grid will become active over time... I've tried sectioning away the regions that become active, but this didn't work... Is there a better way to get around topology change for this filter?

I am sure that at one point it worked in parallel, with the caveat that samples of points or point-data will over-represent values on process boundaries (because ParaView does not have knowledge of how many processes hold any given process-boundary point).

Err, and as I see Ken just mentioned, I only worked on the statistics filters that Temporal Statistics uses under the hood.
