Hi All,

here i share a video showing a little example of wave2foam coupled with dynamic mesh motion. I've modified the waveFlume example:

Thanks for noting the difference I hope you can benefit from my work!

Sure, until now i was working with groovyBC when i need to generate waves, but my principal problem is the wave absortion, and i'm working with a modified version of interDyMFoam where i added a artificial damping coeficient in momentum equation, using a scalar field for act in the zones of interest, i.e. a numerical beach. But the relaxation zones that you implemented seems to work much better, so thank you again.

Hi all

@Jordi: Neat! Is it a free floating object or have you applied mooring lines? You might have noticed, but waves2Foam has already been made ready for a numerical beach; merely two things are missing, namely (i) define the variation(s) of the artificial viscosity and (ii) add the source term in the momentum equation in the solvers. The latter part is really easy, since the needed interface is already in place as can be seen from the wiki. Again it is made with runTime selection in mind.

Kind regards,

Niels

I've used a constraint plane XY and moments of inertia very highs in the three axis (that's the reason of the small pitch), to assure the stability in this simulation test.

Hi, Jordi,

I downloaded the model files you uploaded on
https://sites.google.com/site/jordim...ic-mesh-motion

however, I can not compile the waveDyMFoam successfully. I am sure i followed the steps suggested in Wiki.
