Hello everyone
I want to model previous concrete in a channel of flowing water, I want to know how much water infiltrate through the previous concrete and how much pass over it,can it be done using ANSYS-CFX? How? How to set the boundary at concrete?

In your case, I would start researching
(a) Porous media
(b) Multiphase flow

Yes Right but the problem is that how to set boundary at previous concrete (Porous media)

I don't know what you are modelling or why, but if I guess what you are doing then I suspect you want to model the previous concrete as a porous material. If you are asking how to set up a porous material - then look in the CFX tutorial examples and CFX documentation.

thanks a lot dear for your reply
I want to model: a channel of water, at a section of the channel, there is previous concrete at the bottom of the channel it work like a filter, part of water moves down through the concrete (since its previous) and part of water pass over it, I want to know how much water pass through the previous concrete

It sounds like my previous comment was correct then - "you want to model the previous concrete as a porous material. If you are asking how to set up a porous material - then look in the CFX tutorial examples and CFX documentation."
