How to calculate the cell area
 

Hi, Anybody know how to get the cell area. In Fluent, we can calculate the volume of a cell by C_VOLUME(c,t). But I want to get the area of a cell in y direction (if the cell is hexahedral, the area normal to y direction of the cell is needed to define.

One more question, if I want to know the total area of all cells which are created by an interface normal to y direction in a cell thread. What should I calculate?. Please give me a clue.
