I set initial values of gamma in some cells to 1.0 and the rest to 0.0. I wanted to simulate a mixing of two fluids, however I get always the same message even using smaller time steps: ... Reading transportProperties Selecting incompressible transport model Newtonian Selecting incompressible transport model Newtonian Calculating field g.h time step continuity errors : sum local = 0, global = 0, cumulative = 0 Starting time loop Max Courant Number = -0 Time = 0.001 Liquid phase volume fraction = 0 Min(gamma) = 0 Max(gamma) = 0 Liquid phase volume fraction = 0 Min(gamma) = 0 Max(gamma) = 0 Liquid phase volume fraction = 0 Min(gamma) = 0 Max(gamma) = 0 Liquid phase volume fraction = 0 Min(gamma) = 0 Max(gamma) = 0 time step continuity errors : sum local = nan, global = nan, cumulative = nan ExecutionTime = 0.12 s ... Does anyone know what might be wrong?
