Time series and spectral analysis #20

Closed pcosme closed 3 years ago

pcosme commented 4 years ago

Routines to analyse the data obtained from the simulation should be implemented (or re-implemented) preferentially in the analysis.cpp file.

The old routine of envelope detection seems to be working.

I'll make a new analysis code to deal with the density and velocity instead of current and potential as in analysis.cpp

Routines moved to TimeSeries.cpp check the _run_singletest.sh to see how to run: *./TimeSeries $(wc -l slice) $s** it requires the total number of lines in the file (given by the wc -l) The new code can perform now:

saturation values of density and velocity either at x=0 and x=L
time to attain 99% of saturation of the previous quantities

A study of the evolution of these quantities with the parameters S and Vf should be performed

On commit c7ea064c530a95df8213a32ad5584e898bfde6eb I've added a python script intended to implement a spectrogram from the 1D signal. It should be further optimised, regarding the windowing and frequency/time resolution
