Hi all! It never occurred to me to come across the term 'propagation' to describe any of the terms in the Navier-Stokes equations. I seem to only have encountered this word as a synonym for transmission (waves, sound, etc) and only in broad/vague sense.
In the context of the Telemac-2D documentation, in contrast, propagation is pretty recurrent and seems to have a specific meaning. For example, there are references to the propagation-diffusion step in a predictor-corrector scheme, while propagation can also be linearised.
However, I could find no definition nor a set of equations to prop up speculations, whether in the user and reference manuals, in the dico file or on a shallow query on Google.
Could someone, please, point me to a definition of propagation that applies to the Telemac implementation?
Thanks for clarifying this for me.
Best regards,
Giordano Lipari
