Mixing of two fluids moving in a long pipe
 
I want to simulate a parcel composed of two fluids moving with the mean flow velocity. I try to implement DyM in twoLiquidMixingFoam, but when I try to simulate a case the delta of time begins to decrease until it finally stops the solution ... can someone help me?

twoLiquidMixingFoam includes setDeltaT.H which resets the time step to maintain a constant maximum Courant number. Check the description of setDeltaT.H and also check the adjustTimeStep configuration in the controlDict
