I'm a new openFOAM user, I'm trying to computate the free surface ship problem. Until now I'm trying 2 different approach:
1) I try to run the simulation of the wigley in a structured mesh with the OF1.6(case made by Eric Paterson (thanks for the link!!!!)) but after 1 second of physical time the water level go down. (I use the interFoam solver)
2) I try the DTMB case using the snappyHexMesh but only after few iteration the pressure field diverge.
Some one has solved a similar problem? Could gave me the right Boundary condition and the case condition?

Thanks a lot.

Hi Diego

I'm a new OF user too and I'm working on a similar project. I suggest you to have a look at this different cases:

where you could find an archive named my6DOFFoam which is an example of floating object.

2- http://openfoam-extend.svn.sourcefor...ydrodynamicIG/
which contains one sovler called shipFoam, BC's library (waveBC) and tutorials.

I've managed to compile them with more or less difficulty but I think it's a good startpoint.

Good luck!
