Interior boundary and slip condition

Tharanga · September 10, 2015, 20:37

Hi all,

I have interior boundaries in my model and I think interior boundaries has slip condition as a default. Is there any method to change slip to no slip condition?. Please give some suggestions. Thank you.

Make your boundary a wall? Otherwise, how would you have a no-slip?

Thank you for the reply,
I have two domains, fluid is leaking to the second domain through this interior surface. I cant change this in to a wall because there won't be any leakage. This is bit tricky.

How about a porous wall? This gives you the leakage, and is still a wall so the no-slip condition can be applied.
