Hi,

I know that in T2D, the velocity is averaged and located at 40% of the water column above the seabed. What about T3D?

Assuming I have a 3D model of 6 layers. Let's say I need to extract the time-series for a point located on layer 4. Would the extracted velocity value be calculated exactly at layer 4? or averaged for the whole water depth above layer 4 and located at 60% of that depth (from the surface)? or averaged for the water depth between the seabed and layer 4 and located at 60% of that depth (from layer 4)?

Secondly, if I select in bluekenue 3 layers, say 2,3 and 4. Would the extracted velocity be for the averaged depth of the 3 layers or just layer 4 will be taken into consideration as it's the top selected layer?

Thanks,
Mohammed

No averaging is performed, by definition (3D simulation). Look at the manuals and test cases for more information. Hope it helps! Regards PL
