Hi Max,
If there is a fluid on one side and solid on the other side, then a wall at the interface should be given coupled wall condition to balance the transfer at the surface. If it is a wall, between two fluids, for the flow to happen, the interface should be 'interior'. For heat transfer, what should be the condition at the interface? |

Hello,
I would like to calculate the radiation from the liquid metal surface to the surrounding walls and the lid, in a half filled ladle in FLUENT. I am using the multiphase VOF model with liquid metal half filled in the ladle and hot air above it. If anyone had an experience in simulating such a problem, kindly help me. |

Thank you Pakk.
I have modeled flow through porous medium with adjacent fluid media in GAMBIT. If the edge in between porous medium region and fluid region is given as interface in GAMBIT, there is nothing left for mesh interface in FLUENT.If I try to initialize the flow in FLUENT, error is displayed regarding these interfaces. So,I gave these edges as interior.I could then see a converged solution. Is giving interior correct? |

I don't know about Gambit, maybe Gambit uses different terms.
But I know that as soon as you are in Fluent, you should see "interface" at those places. If you see "interior", you are talking about something else. |
