Volume in fluent 2d
Hi.
when we use fluent 2D (2d or 2ddp), at the begining fluent display a statistics about volume and face area (minimum volume, maximum volume, total volume, minimum face area ....etc). I want to ask: what represent the volume in this case????

LuckyTran, thanks for your reply. in my question I meant what represent the volume in 2D? regards

Hence, even for a 2D problem, there is still a 3D representation, with volumes and all. You can also think of it mathematically, 2D is just 3D with everything the same in one direction. It's not that a 2D problem only has 2 dimensions, just that the 3rd dimension is either ignored or treated differently. 
LuckyTran,Hi.
I get it. Thanks for these clarifications and explanations. 
the volume of a 2d cell is simply the area of the cell multiplied by unit depth
so, for a cell with area A, it's volume V=A*1 m^3 
the volume of 2d cell is the area of the cell multiplied by unit depth.

When i return the value of C_VOLUME(c,t), I get zero for a 2D mesh ! So how do we know the third dimension ? 
Dear,
Fluent doesn't identify the Macro C_VOLUME(c,t) for 2d mesh, you should instead use the cell area Macro to return the value of the cell area...then the volume of your cell will simply be the returned cell area multiplied by unit depth of 1m.
