Dear Foamers,

My eventual goal is to simulate multiple ships floating side-by-side in waves.

As a first step, I have modified the floatingObject example under the interDyMFoam sub-directory to model 2 boxes. I have tried to refine my mesh and adjust the time steps, but my two attempts seemed to stop at the same point in time regardless of the mesh refinement.

The error message that I am getting is as follows:

MULES: Solving for alpha1
Liquid phase volume fraction = 0.503994516429  Min(alpha1) = -2.545080202e-15  Max(alpha1) = 1.07101310392e+292

I have also attached my blockMesh file and the dictionary files under the system directory. Really appreciate if anyone could help me with this problem.

Thank you.
