Interfaces in star ccm+

Suyash26 · December 3, 2012, 04:17

Hi,
Can anyone briefly give me the information regarding the types interfaces that we need to create between two different states like solid and liquid.
My model is as follow:
I have a room exposed to surrounding. Solar radiations are incident on the walls of the room(Or constant heat flux). So heat is first conducted through the walls of the room and then to the air inside the room through convection.

So what kind of interface/s I need to create between wall and fluid inside the room and any boundary condition that I need to give on inner side of wall?

I am new to star ccm+ and I need the help while creating the interfaces between the two parts.

If you are modelling (meshing) both the wall and the air inside then you only need to create an in-place interface between the solid and fluid boundary. It will be a contact interface by default. The program will take care of the rest.

Hey Ladnam, thanks for the reply.
I also want to ask is there a way to calculate inside humidity of room in star ccm+?
