Alphawater go down abruptly to a small number

Hi Foamers,
I am about to use interFoam for mudflow simulations using Herschel-Bulkley rheology. prior to my main job, I am simulating the conventional 3d dambreak by only changing the rheology of the fluid and assuming laminar flow. When I do simulate by varying the parameters tau0 and k, for certain combination of these parameters, I am facing this problem: - After certain time step the fluid with alphawater=1.0 is disappearing. At some point of time alpha always go down abruptly to a very small number (order of 1.0e-5 even lower). - I can't understand the physical implication. Does this have anything with my mesh size? |
