Name the faces of Interfaces while meshing,,
In Fluent interface > create interface >Select source face and target faces.. If you are working on heat transfer, you can opt for Coupled wall.. Define two different fluid properties at beginning.. For the flow where air adjacent to liquid this may work.. For complex cases it may nt.. |

After cell-zone conditions> Mesh Interfaces if its Fluent 13/14.. older you can get by menu bar.. Define> Mesh Interfaces..
Bt you wont be able to access it unless you define it while meshing.. Undefined faces seems to be considered as wall by default.. |

I did as per your saying, but it is not taking the interface zones. I had defined its top surface as interface.

If in yur case two fluids are one above other u need to define the lower most face of upper fluid as one face (say source face) and uppermost face of lower fluid as other face(target face).. to create interfaces min. 2 faces are required as per my knowledge.. Even if you not name it while meshing it will generate automatically but locating that face will need some effort.. So proceed as above.. Important Most step- In Boundary Conditions select the face of interface yur planning to create.. By default it will set some BC (say wall, inlet etc.) Change it to Interface for both faces.. Without this Mesh interface option will not gt highlighted.. Its well defined in User manual.. U can have a look.. |
