PIVUQ

[Francesco Bardi]

Dear All,

I am trying to use PIVUQ to estimate the uncertainty of PIV data obtained with OpenPIV.

When using the function pivuq.disparity.sws ( https://pivuq.readthedocs.io/en/latest/api/disparity.html#pivuq.disparity.sws )  which window_size and grid_size should I use?

Should I use the same values that I used to compute the velocity field?

Thank you!

Francesco

Hi Francesco, 

I think best is to follow these examples. 

https://github.com/lento234/pivuq/tree/main/examples

I think those self-explanatory. You’re also welcome to raise a Github issue on that repo to the original author, Lento. 

Regards,

Alex
