I am doing my project work in hydrodynamic modeling. I want to know that which turbulence model is best for estuaries? I have to employ a dynamic (time varying) boundary condition at the entrance of the domain, how can I do that in fluent? Is there any option to provide dynamic boundary condition? If anybody can let me know,it will be helpful for me. Thanks for help in advance

User defined function that will call the flow-time and set whatever you want accordingly
