time step continuity errors

Hello guys,

I have the following error when I run the simulation. I cannot understand what it means!!! I am new to Foam, CFD as well as C++. Please help!!

diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0
DILUPBiCG: Solving for Ux, Initial residual = 0, Final residual = 0, No Iterations 0
DILUPBiCG: Solving for Uy, Initial residual = 1, Final residual = 6.95187e-06, No Iterations 6
DILUPBiCG: Solving for Uz, Initial residual = 0, Final residual = 0, No Iterations 0
DILUPBiCG: Solving for h, Initial residual = 1, Final residual = 1.47528e-06, No Iterations 8
DICPCG: Solving for p, Initial residual = 1, Final residual = 0.0827294, No Iterations 17
diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0
time step continuity errors : sum local = 0.0115917, global = 0.000265254, cumulative = 0.000265254
DICPCG: Solving for p, Initial residual = 0.571673, Final residual = 6.48667e-07, No Iterations 68
diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0
time step continuity errors : sum local = 1.41866e-07, global = -6.07745e-13, cumulative = 0.000265254

PS: My checkMesh shows no errors too. the meshing seems ok!!

never mind.... i figured it out. there were some mistakes in the boundary conditions i specified.
