hi
i m trying to run interFoam solver but i see that volume fraction under zero smoothSolver: Solving for alpha.water, Initial residual = 3.57599e-06, Final residual = 1.53736e-10, No Iterations 1 Phase-1 volume fraction = -1.70339e-07 Min(alpha1) = -0.0117843 Max(alpha1) = 1 MULES: Correcting alpha.water DICPCG: Solving for p_rgh, Initial residual = 0.0702105, Final residual = 0.00350965, No Iterations 15 time step continuity errors : sum local = 5.78837e-10, global = 6.94181e-22, cumulative = 3.66196 DICPCG: Solving for p_rgh, Initial residual = 0.0508963, Final residual = 0.00249176, No Iterations 344 ExecutionTime = 5860.9 s ClockTime = 5926 s smoothSolver: Solving for alpha.water, Initial residual = 3.66996e-06, Final residual = 1.92495e-10, No Iterations 1 Phase-1 volume fraction = -1.71841e-07 Min(alpha1) = -0.0117813 Max(alpha1) = 1 MULES: Correcting alpha.water DICPCG: Solving for p_rgh, Initial residual = 0.0505673, Final residual = 0.00226451, No Iterations 382 time step continuity errors : sum local = 7.86302e-10, global = 2.78746e-22, cumulative = 3.66196 DICPCG: Solving for p_rgh, Initial residual = 0.754927, Final residual = 0.026304, No Iterations 3 time step continuity errors : sum local = 7.22643e-09, global = -3.92847e-23, cumulative = 3.66196 i dont understand better this if some one can expain thanks |
