I am modelling a VOF Model fuel/air mixture for the configuration as attached below. It consists of 8 sideinlets and one main inlet and i have used velocity inlet as the boundary condition for all the inlets. The solution is diverging while using a PISO solver however i am getting convergence for the explicit coupled solver. However, the residual plot goes up and again comes down for the volume fraction and the solution is not getting converged at every step. I tried running the simulation until 1600 iterations but the issue is not resolved.
I assume my boundary conditions are proper. Inlets- Velocity Inlet Outlet-Pressure outlet Symmetry and wall conditions. My mesh check is proper. Please advice me on how to get the solution converged at every step as i am beginner with fluent-cfd. Kindly help. 11.jpg |
