Hello

I use the FLOW-3D V9.4.

In this version, I set the diameter about 0.002m, and set the density about 2651.4 in physics -> sediment scour.

And then, in the boundaries, I ues the volume flow rate.

In this option, I set the sediment concentration about 795.42.

However, the result is wrong.

Where do I set wrong?

Thanks.

Dear JunWei Wang.

I think you'll need another BC. You should use Discharge BC with water heights. In the other way you'll probably get super critical flow. IMHO you could you could use WH only.
