Hi Niels,
I'm going to use your wave generation toolbox for my thesis. I've got some questions,I would be grateful if you answer them.
Can I add turbulence properties to waveFlume case and run it for RASmodel? Does it work well?
I'm going to use developed solvers like shipFoam or navalFoam. Is there a guide that how I can integrate these solvers with your toolbox? I've seen the guide for making waveDyMFoam solver. Should I follow the same steps?
Also, why it's needed to put all the wave properties in the waveProperties file when it's given firstStokes? Isn't Height, time Period, depth enough as inputs?

Best regards
Maryam

Hi Maryam,

The turbulence modelling is already available in waveFoam, but OpenFoam does not provide a useful set of turbulence models for two-phase (incompressible) flows. I would recommend you to read our article cited on the Wiki (Jacobsen et al, 2012).

With respect to a guide on coupling with either shipFoam or NavalPack, then I have not really worked with any of these packages/solvers, but I think it should be straightforward. Especially, if you also look into the guide on interDyMFoam.

Kind regards,

Niels

Hi Niel,

I had a look at your paper. You used k-w turbulence model which I think is not provided by openFoam. In tutorioals, I couln't find any case with turbulence model. They were all laminar. So I couldn't understand, how I should add turbulence to the cases.

I followed the instruction at first to make waveDyMFoam. The instruction wasn't compelely working. At last by changing some things, I could make the solver. But after runing it for a case it gives the error below:

-> FOAM Warning : 
    From function dlLibraryTable::open(const dictionary& dict, const word& libsEntry, const TablePtr tablePtr)
    in file lnInclude/dlLibraryTableTemplates.C at line 68

Do you know what's it due to?
Thanks so much for your consideration.
Best regards,
Maryam

Hallo all,

@Maryam: I believe you need to link to libwaves2FoamSampling as well.
Furthermore, none of the tutorials are run with a turbulence model, because none of the standard (incompressible) turbulence models in OF can (my personal opinion) be used for free surface flows, because the diffusion across the free surface is too large, when the density is not accounted for. I have never come around to put corrected turbulence model(s) into waves2Foam, so for now, I recommend that you create your own, e.g. according to our article or any other turbulence model of your preference.

[Moderator note: answers to other posts removed, since the original post has been copied to the other as well.]

Kind regards,

Hi Niels,
I don't have "libwaves2FoamSampling.so" in my wave2foam. The list of my lib is attached below:

/home/kzheng/OpenFOAM/kzheng-4.0/platforms/linux64GccDPInt32Opt/lib
libOceanWave3D.so libOceanWave3DBuild.a libwaves2Foam.so libwaves2FoamPorosity.so libwaves2FoamProcessing.so

Could you tell me how to get the libwaves2FoamSampling.so? BecauseI need to use SurfaceElevation function.


Best regards,
Kun

Hi Kun,

As you will see in this release note:

Release of a Wave Generation and Absorption Toolbox for OF

The sampling utilities are not supported on more recent versions of OpenFoam due to a restructuring of the functionObject environment. There is currently no time horizon for when the sampling utilities are supported on the most recent versions of OpenFoam and OpenFoam+.

Kind regards,

Niels

Hi Niels,

Thank you for your explanation. I think I have to install the previous versions of OpenFoam.

Best regards,
