how to include a souce term in cells adjucent to the a specific wall
 

hello everyone
I am modelling a porous jump across a specific wall in my domain and i have to include the source and sink term on the cells adjucent to the wall on the both side.
I dont know how to call these cells????
thanks in advance for your time and concern

In Fluent, basically the idea is to separate out a cell zone adjacent to the boundary face you are interested.

Step 1 (mark the boundary face for use in later separation of the cell zone)
Adapt - > Boundary -> (Options: Cell distance; Number of cells: 1; Boundary zone: say "wall1") -> Mark

Step 2 (separate out your desired cells)
Mesh -> Separate -> Cells (Options: Mark, Registers: your previously marked face will appear here; Zones: the parent zone you will create the new cell zone from). Then "separate".

Now you will have your cell zone that is adjacent to your boundary face available for use to specify source or sink.
