Inline structure – radial gates

[Mirko Mu]

Hi everyone,
i’m trying to simulate a weir (ogee crested) with 3 radial gates 10mx10m in steady flow condition.
After the simulation, when i see the results in the inline structure output i noticed that the whole discharge that i used in the simulation is splitted in two components: Qweir and Qgates.

Starting from the fact that in my simulation i consider all the three gates totally opened (3 gates high 10 m), i don’t understand the meaning of the Qweir and Qgates. I post also the image of the output table.

Another question is: if i simulate this weir with all the gates fully opened and the same weir without gates i was expecting to have the same results (or similar) but i observe differences of 50-60 cm. Why?

Anyone can help me to understand?

Thanks a lot

Mirko

IN the weir editor utilize the optimization option to allow flow to be split accordingly
