Dear,

 

I am modeling a wave-current interaction problem in an open channel, please see picture below defining my domain and the boundary locations. I have 3 questions, if you could please assist me with:

1- At the outlet boundary location: I need to apply a velocity only at the water phase, not air. How is this possible?

2- At the inlet boundary location: Similarly, I need to assign a wave BC only at the water phase, however, only for the first portion of the inlet specified a bit above the bed level up to the water free surface. Again how is it possible?

3- At the inlet boundary location: Similarly, I need to assign a velocity only at the water phase, however, only for the second portion of the inlet marked close to the bed level. Which is the solution?

Thank you!

I would like to add that I am simulating this problem as a multiphase VOF model.

I don't know why I am not receiving any reply messages. If I should provide more detail, please let me know.

Good morning all,

If any of you could give me any suggestions and possible solutions for assigning different BCs to different materials at one boundary location, will be a great help. When I change the phase from mixture to water in the BC, I cannot define any waves. Please see below pictures.

 

Thanks in advance!
