How do you create a Weir(waterfall dam) geometry/meshing? [video included]
 

Hey all,

I'm new to fluent (2 months) and am asked to create a Weir among other things in a 80 ft. x 16 ft. x 5.5 ft. fish tank (aquaculture - mixed cell raceway).

Can somebody help me in the creation of this or give me some tips to build it? I imagine it must look like this after completion:

I already have the tank complete with a few drains, but I'm really unsure how to get the fluid to look like that or start that way, is that a build in the 3d geometry? how do i make that an outlet?
