Hi Seemit,
I only managed to take a quick look at your model and I have two comments. It is safer to start prescribed velocities in a time dependent analysis with zero so that the first time step solution is close to the initial conditions. Also it’s not suitable to put velocity boundary conditions at both inlet and outlet. Switch one to pressure.
