Hello, Foamers

I'm trying to solve flow past a floating square box.
The solver is interFoam(Multiphase water, air).
The domain, suface mesh, volume mesh are generated by Pointwise and I set boundary conditions as below :
Inlet, oulet, atmosphere : patch
bottom, midplane, side : symmetry
box : wall

Volume mesh is composed of tetrahedron mesh.
Mesh quality checked by checkMesh utility was fine with some skew cells.

The problem is that Iterations for alpha.water and k, epsilon is 1000 and they blow up later...
I already faced this situation when the mesh was structured mesh.. I thought unstructured mesh will be a solution for this situation but... nothing changed
Here is terminal output

I guess this is because of initial condition or improper numerical scheme and numerical solver.. so, I attached my fvSolution, fvScheme, controlDict in system folder and 0.org folder..
Have anyone experienced this too much iteration problem? If so, how can I solve this problem? :confused:
