I am trying to simulate a bubble column with twoPhaseEulerFoam. When running my case alpha1 reaches values that should not be possible.
Courant Number mean: 0.00734422 max: 0.637501 Max Ur Courant Number = 0.453228 Time = 0.675 MULES: Solving for alpha1 Dispersed phase volume fraction = 0.000455625 Min(alpha1) = -0.00187942 Max(alpha1) = 1 MULES: Solving for alpha1 Dispersed phase volume fraction = 0.000455625 Min(alpha1) = -0.540265 Max(alpha1) = 1

Try using a much smaller time step.
