I'm still pretty new in the CFD modelling world.
Can anyone advise me how to define a inlet for a tidal basin in Fluent? The water level and the velocity at the inlet vary in time due to the tide cycle.
Depending on what you are trying to accomplish, you might want to look at some of the ocean modeling codes that exist to model a tidel inlet. The Princeton Ocean Model (POM) is one of the most well-known of these and is relatively easy to setup. Other examples include
all of which have an active user community with examples.
