Re: OBJECT IMPACT ON WATER

I will experiment with VoF, with a moving body of water. In the meantime, I extend my thanks to you folks.
I'll keep updating, and will make sure to share the model I'm using on this forum.

Stay cool folks,

Re: OBJECT IMPACT ON WATER

Hi, I appreciate the time you take. My Reynolds is in the between 10^4 and 10^5 ( depends on the result of my previous model which I'm finishing up as I speak ). The cylinder would have a round nose, would be completely rigid, and I would imagine the cylinder could have a rotation on the Y-axis (see...

Re: OBJECT IMPACT ON WATER

Hi again folks, thanks for the answers. I'll look into VoF (I had my eye on that feature). Mr.Storti result are exactly what I need and my next plan is to get in touch with him(these videos are awesome). That ongoing research work at France Energies Marine seems quite appropriate; I really need to g...

OBJECT IMPACT ON WATER

Hi folks, it's me again, now querying for opinions. I want to simulate a cylinder entering a water volume with an initial velocity . SIM_MODEL.png I tried using the ALE module, without success. Can anybody think of a model that could achieve said results ? The main trouble comes from finding what bo...

Re: Issue with restart of an ALE case

Thanks Yvan, I think my case isnt really possible within Code_Saturne. I would like to simulate the speed loss of a cylinde when entering water, I don't think Saturne's default tools can help me with it . I'll make a new post asking for opinions on the feasibility of said simulation. You stay awesom...

Re: Issue with restart of an ALE case

Hi again, I don't have any movement before. I set a very simple case with an inlet, an outlet, a wall and symmetry conditions for the other sides of the box. ALE conditions are either all fixed or all sliding(I tried both ), with the wall being an internal coupling. I have set all my damping, mass, ...

Re: Issue with restart of an ALE case

Hi Yvan, thanks for your answer, I understand it might only be a warning. Although i don't any explanations as to why my model doesnt move at all during the simulation. Do you have any idea why ? or do you know of any typical issues that may arise ? The convergence tool doesnt even show anything for...

Issue with restart of an ALE case

Hi folks, I am running an ALE case, with a typical fluid init phase, and a restart for the mesh movement, but I encounter the following issue : Start reading Reading dimensions complete Reading the previous time step number (restarting computation) NTPABS = 500 Reading the previous time step number ...
