Thank you for this information. Here are some suggestions:

  • Please make sure you are converging every time-step. Please increase the maximum number of iterations per time-step to 20. This will allow the solution to achieve the desired convergence residual criteria set. This is important for a transient problem.

  • Also, please make sure you have sufficiently low time-step such that the Courant number is close to 1 or lower. You can read more about this in the Fluent Users guide.

  • Also, you do not need to use a velocity inlet boundary condition. Please refer to my image from a previous post. You can use pressure outlet on all three ends (with 0 backflow VF of water, similar to the way you set-up).

Please make these changes and let me know your findings.

Thank you.

Best Regards,
