How to define interface
 
Hi all, I am new to CFD please help me

I have two blocks of different materails and they are put together in contact of each other. I have boundary conditions of opposing sides. How to define interface between them and how to model it in fluent.

hi!

the manual is in this case very helpful!
set the both surfaces under boundary conditions to interface.
then go to define->grid interfaces and connect the two interfaces.
finished!

you're welcome.

by the way be careful if you're using an udf with loops over your wall boundaries. fluent generates for interfaces additional wall boundaries without any cells ;)
