Hi there
I want to remodel the deposition of bidisperse sediment in flume with the Flow3D (version 10) sediment and scour model, which was modeled as a test case in Flow Science Technical Note TN-85.

For Case D in this technical note ( which case has equal proportions of fine and coarse sediment), I don't know where I should define the proportion of sediments in the Flow 3D v.10.?

Moreover, I want to know what value I should specify for suspended sediment concentration of fine and coarse sediment in initial condition, for example at mentioned case?

Any body can help me?

thank you.

Hello

You can define volume fractions of the various sediments in Packed Sediment Fraction which is located in Component properties.

about your second question:
In this case you need to create a fluid region and then you can define suspended sediment concentration for each species.
