hello
is code_saturne able to calculate ship's wave making resistance?? if not why?

Re: finding wave making resistance
Hello,
I would say it's not possible since saturne do not have capabilities for computation of fluids interface like VOF or level set.
I've seen some dev regarding free surface computation with ALE formulation but i don't think it is on the main dev branch (i would say it was some Manchester work) and not sure it was capable of such computations.
So using saturne will limit you to double model...
If anybody has more precise information, i am also interested...

Re: finding wave making resistance
Hello,
Actually, there is no VOF or level set in Code_Saturne, but ALE has been in the code for quite a while, and is not restricted to old "Manchester work" (most past developments in Manchester were for turbulence modelling, with one rotor/stator application and most have been merged into the code. Current work is more application oriented. Since we have this web site, it is also much easier for our colleagues in Manchester to keep their versions in sync and provide their feedback and suggestions on the "main" version).
The friction aspect of a moving boat can be simply modelled by limiting the computational domain to the water's surface. I have no idea how strong the wave making resistance (energy dissipated as waves) is compared to that. I assume this could be computed using ALE, though I'm not sure what sort of ALE boundary conditions would be needed for that (I just tried Googling for "CFD wave making resistance", and it seems to provide quite a few links and articles; I'll let you sort out which ones are most applicable, and what best practices recommend).
Regards,
Yvan
