Hi,

a user’s question under one of my YouTube videos made me realize that when it comes to convective film and radiation loads, amplitudes are supported only for sink temperatures (`*FILM, AMPLITUDE` and `*RADIATE, AMPLITUDE`), not for film coefficient and emissivity (`*FILM, FILM AMPLITUDE` and `*RADIATE, RADIATION AMPLITUDE`). I think that it would be nice if those could be implemented as well.

Yes, this is what I am looking for.

It was implemented some time ago.
