Dear OpenFOAM Community and forum users,

I would be very thankfull for any advice. I am currently dealing with ship resistance in shallow waters, using a starCCM+ mesh. The domain is pretty simple, (Inlet / Outlet / Bottom / Side1 & 2 / Hull / Atmosphere) meshed around the KCS HULL Model, approximately 6x10^6 Cells. I use interFoam ver. 4.10, using the DTC Interfoam tutorial. No Mesh morphing, the ship is fixed. After a few timesteps, the simulation collapses with following message:

 PIMPLE: iteration 1
  smoothSolver:  Solving for alpha.water, Initial residual = 7.89558e-07, Final residual = 3.7645e-10, No Iterations 1

Do you have any Ideas?

Kind regards.

Hi,

Did you solved this issue? I am also facing similar issue in OPENFOAM. I imported mesh from STARCCM and modified the setup of DTC hull (Given in tutorials). This mesh works fine in Starccm. But the resistance value shoots up in OPENFOAM. I only changed the bottom boundary condition to "wall" from "symmetry plane".
