Get data at a point outside the node. 7 years 6 months ago #26228

jegatam	Hi everyone How can I get data out of the node? I'm using other programs like matlab interpolating points, but I would like to use Bluekenue Thanks Joaquin

Hello Joaquin,

What you want is to interpolate data to a point inside an element?

If this is the case, I think BlueKenue is not the program to do it. It is more a visualization tool. I suggest you to keep using Matlab or, if the problem is the license, switch to Python or even Fortran.

If what you seek is a method to interpolate the data to an arbitrary point inside an element, search for "Baricentric Interpolation". If you need help with that, I have some code already written in Matlab and Fortran that does it.

Best regards,

Phelype

For example, on page 96 if you have a set of points you could extract interpolated time series for each of those points. Kindly, Alan

Serrer OFFLINE Moderator Posts: 720 Thank you received: 304	Hi Phelype, It's usually best to have read the documentation before making recommendations about a particular software. Just sayin'... Hi Joaquin, Some Blue Kenue techniques that provide spatially interpolated values. - "Live Cursor" - "Map Object" - "Extract TimeSeries At Multiple Points" - "Extract TimeSeries Along a Line" Regards...

Hi everyone

Phelype,
I understand your point, my idea was to get some data straight from the bluekenue and then do a post analysis. Anyway, I'm interested in your code, thanks
I'll talk to you internally.

Kindly and Martin, I made your recommendations, finally generate a streamline i2s file and use the option "extract timeseries along a line" but when I get the file I get a data precision of 10-6, it is possible to get a better precision or to modify it. thanks

Regards

Joaquin
