void init1Dspectrum

(

)

Initialise the 1D spectrum output routine, used to output the spectrum This routine print the mode ks in the first line It also counts the number of mode in each shell and output it in the second line of OUTPUT_SPECTRUM_FILENAME

Here is the call graph for this function:

Here is the caller graph for this function:

void output1Dspectrum	(	const struct Field	fldi,
		const double	ti
	)

Output the transport spectrum in a file (OUTPUT_SPECTRUM_FILENAME) This routine is called only when shear is present.

Parameters:

fldi,:	field from which the transport is computed
ti,:	current time

Here is the call graph for this function:

Here is the caller graph for this function:

void write_spectrum	(	const double complex	wi[],
		const double complex	wj[],
		const double	ti
	)

compute a shell-integrated spectrum of the tensor real(wi*wj+) and write it on OUTPUT_SPECTRUM_FILENAME

Parameters:

wi	1st double complex array from which the spectrum has to be deduced
wj	2nd double complex array from which the spectrum has to be deduced
ti	Current time
