[Paraview] Import list of data points to probe and export time series CSV data

[E. Markus]

Hi,

I am a student researcher using Paraview for the first time. I have question.. hopefully someone can help me.

I have several hundred *.vtu files from a various flow simulations at incremental time steps.  

The data in each contains the x,y,z location information and the pressure (P) and velocity information(U1, U2, U3)

I would like to programmatically probe and export location and velocity data for each point. I cannot figure out how to do this.

Here is what I’m trying to do:

1) read in a csv list of points I would like to probe at every 5th x-index at certain y and z values, e.g. (0..5..100, 0.05, 0) (x,y,z) - technically, the points are not evenly at every 5, so when using the pipeline browser/properties area, if I input 5, it will select the nearest point to 5. Point Coordinates: 0 however will still read 5.

2) Export probed points at all time points

I found http://www.paraview.org/pipermail/paraview/2011-May/021311.html but it is confusing to me because it doesn’t list the specifics of doing something similar, just the general steps.  

I can and have been doing this manually, but doing so takes me an enormous amount of time because of the time it takes to read the data for each point change (each vtu file is 42MB).

Can someone please help?

Thanks,

Ethan
