About convergence
 
Hi,

I am simulating incompressible flow which has velocity inlet and two pressure boundary conditions.After doing 4000 iterations i found that velocity field is still developing but residuals have gone below 10-5.Also i see that at inlet pressure value is not constant. Can anybody please suggest me what to do in order to get converged solution?

Are you using a turbulence model? You may have to ask yourself the question; Is the flow still developing or has it developed and is just unsteady? You may have to switch to transient and set your own (more appropriate) time-step.
