Thank you very much for sharing, Nils - this is really helpful!
Would you mind to share (a simple version of) the Modelica code as well - just for the sake of being able to copy-paste (for lazy people like me;)?

Thanks, again + regards
Christian
2. christiankeh liked a post in a topic by L Moretti in FFT 3D plot
Let's assume that there is a curve f(a, t) in time domain and we apply FFT to the function, assigning values to a (like a=a1, a2, a3, . . . ., an). Then, as a result we can get n FFT curves in frequency domain, F1(a1,f), F2(a2,f), F3(a3,f), . . . , Fn(an,f).

We want to plot those FFT curves in a 3D plot which has frequency as x axis, "a" as y axis and FFT magnitude as z axis. Can it be done?

Of course yes!!!

This is what we get with the enclosed script:

fft_3D.oml
