I am working with fluent 14 workbench and I am trying to build a model of 2 boxes. when I try to put the mesh it's behave like one part and not 2 part. how can I solve this problem?

thanks for the help

-cut the boxes with option "frozen" in DM
-create an assembly from both parts --> this will make the meshes to match at the interface

Make two parts in design modeller.
Select the box-1 volumes and right click- create new part
Box-2-select all volumes-right click -new part
by this it treat as two different bodies

how to create an assembly from both parts ?

if you want to give interface between two mating surfaces
If you are working as assmebly mesh ( like cut cell) it treat as as assembly body not single body

but I working as assembly mesh?

Now separating two mesh in ANSYS assembly meshing is not possible.so you can mesh individually and save two separate files and import both files one after other in FLUENT merge it in FLUENT
