Vof Wave
I'm doing a thesis about 6 Dof body (an Hull) and waves of first order with STAR CCM+ v4.04.The wave diffuses quickly and become a flat wave in the control field. I put the boundaries of velocity inlet in every external face of dominio except for the face behind the hull where i put pressure outlet.I set a timestep of 0.01 sec. The wave has a lenght of 20 m, amplitude 1 m,current and wind 2,5 m/s. Do you have an idea to solve this problem? Thank You

That the wave becomes flat quickly? |
Yes...I think it's a problem of approssimation...a first order wave has limits and i can't have a wave of certain features with the first order
|
Why only first order?
|
Not only first order...but i'm studying first order...with first order I mean first order of Stokes approssimation theory
|
Ahh ok. That's down my alley :D
Maybe this helps you: http://www.flow3d.com/resources/news...mmer09_02.html |
Thank You, I've already seen this yesterday...it's the reason i wrote that first order have some limits
|
Ok, then I understand your posting right.
Again what is your problem? |
In this moment nothing, i'm simulating a new wave and tomorrow i'll see the result...So i'm waiting...
|
After three days of simulation, 64 sec. in simulation time...it's all good
|
Sounds good. :)
