Hello,


I am modelising waves on a sloped beach using waveFoam solver on openFOAM v2012 but I can't find a way to make it run properly. The Courant number blows up from the very beginning.

Courant Number mean: 760.026 max: 6.86201e+06
Interface Courant Number mean: 0.122699 max: 75619.4
Time = 0.009

PIMPLE: iteration 1
smoothSolver:  Solving for alpha.water, Initial residual = 0.982492, Final residual = 9.63911e-09, No Iterations 12
Phase-1 volume fraction = 2.85527e+13  Min(alpha.water) = -3.91934e+21  Max(alpha.water) = 1.04748e+21
MULES: Correcting alpha.water
Phase-1 volume fraction = 3.01493e+13  Min(alpha.water) = -3.31135e+33  Max(alpha.water) = 4.28531e+33
Relaxing time: 0.01 s
GAMG:  Solving for p_rgh, Initial residual = 0.0638373, Final residual = 1.87173e+114, No Iterations 1000

You will find attached my case that you can run with

./Allrun

.
