Cell centroid and cell volume in general, and in Fluent
Hi
Is there anyone who can explain me how do the cell centroid(c_centroid) and cell volume(C_Volume) functions of Fluent work? What method they use to calculate the centroid and the volume of a cell. Im writing my code, and would like to create functions similar to these.Thanks. 
I don't how fluent does this but the following will work for arbitrary cell geometries:
Code:
Loop faces 
Thank you for your answer. Since i asked i have already find an other method using the divergence theorem (Gauss) to transform volume integrals to surface integrals.

Right, that will work too. I preferred the method I described since it will give the face areas, face centroids, cell volumes and cell centroids in one swipe.
Good luck with your code.
