Hello Everyone,

I want to give an initial velocity in the soil block, for representing the initial soil sliding velocity at some stage in submarine landslide. I want to give the velocity directly on the soil block at initial time but not by the inlet boundary condition (which allows material inflow in the domain). Does it possible to give the initial velocity directly on the soil mass?

Here I have attached an image of the model.

Please help me to figure out this problem.

Thanks in Advance.

Best regards,
Binoy

It would be great if additional information is given in order to help.

Is it a multiphase case ? porous media case ?

Thank you.
It is a multi phase model. And soil is modeled as a non-Newtonian fluid.

You can initialize the velocity of each phase independently.

There are two mechanisms for initialization: global or per domain.

Say domain based, open the domain of interest, go to the Domain Initialization tab, activate and select Fluid Dependent option for Velocity.

Hello Opaque,

Thank you for your reply. But can you please be a bit more specific. In the initialization tab there is a two type of velocity- Cartesian and cylindrical. And in Cartesian I can set velocity in the U direction. but this velocity will impose on full domain- soil as well as water.

Please give suggestion.

Thank you.

If you are running a Eulerian "Inhomogeneous" Multiphase model, there you should be a list of phases under the initialization tab.

If there is no list, you have not setup a Eulerian Multiphase model yet.
