[GAMBIT] Problem in meshing the spillway in Gambit

flow_CH · Today, 07:19

Hello

I am simulating a ogee spillway with aeration duct into the ramp in FLUENT.
Can you answer me how i should define the grids into the Gambit since
with consider the aeration duct, it is hard to me to define the grids,
because the aerator duct remain out of the boundary zone and the air can not enter it. Please see
attached image.
Thanks

do you already have cad geometry or do you have to built it into Gambit?
(I didn't exactly understand your point, maybe with 3d view I could get it)

I built it in solidworks. my point is the air can not enter the aerator with suction of flow(due to negative pressure). upper grid Appropriate when i want to enter the air myself.
