the interface condition is needed for connecting different grid in a model, non matching interface, sliding mesh interface, and so on.
Sliding mesh interface : use in the sliding mesh model, one part of the mesh will move regarding to the other.
Different grid interface : for connecting different kind of grid without transition. for exemple, hexa with tetra without pyramidal element. Fluent interpolate the result a mesh interface from one grid to the other.
Non matching interface : grid with diferent shape and/or with different position of their nodes. If you have the fluent tutorials take a look at the film cooling exemple.
the interior condition is usefull if you have surfaces in you model which are part of the fluid. If you don't use interior condition gambit can considerer them as wall.
the internal condition is quite the same as interior but it will be merge in the adjacent interiors in the final mesh if you use tgrid. I think that this condition is useless if you use gambit. |
