Hi,

I try to simulate the swell for a boat hull. I had already a look into the code saturne tutorial. Code saturne seems not to be able to handle this problem cause of the missing possiblity to have fluids with different density (water/air)???

OpenFoam is very complicated (within CAE I have only 3 years experience in nastran).

Is there any suggestion which code is possible to handle the problem or perhaps is there an example/tutorial that deals with a similar one?

Would be grateful for every help!

Cheers

Thomas

Hi,

I am not so sure but I think that Code-Saturne can handle multi-phase flow... but I don't know if and how the free surface is handled.

The problem that you are trying to solve is relatively difficult, but I think that Gerris Flow Solver ( gfs.sourceforge.net ) seems to be able to handle this case in an elegant way thanks to its automatic adaptative octree meshing method and its VoF capabilities.
See this example for more information:
gfs.sourceforge.net/examples/examples/ship.html#htoc10

If it works for you, don't hesitate to post your feedback on this forum!!

Hi,

I don't think Code_Saturne can answer your problem. It only deals with single-phase flows, or Euler-Lagrange two-phase flows for particles tracking. It neither handles Euler-Euler two-phase flows nor has VOF-like capabilities.

Gerris Flow Solver might be an option indeed.

David

Hi,

Thanks for the replies, I will try with Gerris Flow Solver.
