Hi,
maybe it is usefull for someone:
(define (display-fluxes-at-step . fluxes)
(lambda ()
(if (not (null? fluxes))
(apply display-csv
(append (list (string-append "flux" (number->string (meep-time)))
(get-flux-freqs (car fluxes)))
(map get-fluxes fluxes))))
))
and call like
(run-until 300 (at-every 10 (display-fluxes-at-step f)))
it is just a hack of the old display-flux function
regards
Andreas
