nI am using Adaptive, Incremental time steps. Number of time steps = 20 because it converges before that itself. Courant number is 2. Initial time step size = 1e-5.nShould I be looking into injections for this rather than just VOF?.nAnd about the volume fraction error I get above, can you suggest what I can do about this?. Because the oil drop and the plastic exist in the same region, and I cannot set both to 1. nThanks for the help.n
