Selective boundary/interface permeability

Antanas · March 30, 2012, 01:52

Hello!

I wonder is there any possibilty in CFX to make boundary or domain interface permeable for one fluid and impermeable for other (or for solid particles)?

What type of flow? What type of mixture? Multi-what - phase/component/both/something else?

There will be a way regardless of what type of simulation you are doing.

Multiphase flow. One fluid, one solid. Fluid flows through boundary, solid doesn't.
It's something like filter.

Not sure, but you might be able to do this with an interface.

Why are you doing this? What physical process is it modelling?
