Dear experts:
I want to simulate pipe flow. I selected no sharp interface. I set up inlet is specific velocity boundary and outlet is specific pressure boundary. When it was simulating that the pressure iteration did not converge. How did I solve the problem? |

You can try set the initial velocity and pressure equal to the boundary values and use a smaller initial time step size to help the solution adjust to the boundary conditions.
