Resistance prediction in shallow water using OpenFoam
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:
Code:
PIMPLE: iteration 1
smoothSolver: Solving for alpha.water, Initial residual = 7.89558e-07, Final residual = 3.7645e-10, No Iterations 1
Phase-1 volume fraction = 0.284503 Min(alpha.water) = -0.150908 Max(alpha.water) = 17.5372
Applying the previous iteration compression flux
