Default Spillway modelling: doubt about dimension

Dear All,

how do you set the dimensions of your Flow3d model?

In the case of Flow over a Spillway, do you model the real dimensions of the

spillway or it is better to scale them?

Thanks in advance.

it might be preferable to model the real dimension. thats one of the advantages using CFD instead of doing experiment. if you scale the geometry in CFD or experiment, you most likely will also need to scale the flow velocity, fluid properties, etc.
