 April 8, 2008, 12:41 Face Area #1 Corentin Guest   Posts: n/a Hi! I am trying to obtain the area of a cell. There are a lot of functions with F_... but I can't find anyone that would give me the area of a face. There is the F_AREA function of course, but it is returning a... vector. What the hell is that? It seems that the norm of this vector would give me the area. Is that really true? If so, this is an extremely strange way to get the area, from my point of view... Anyway, I tried this, with the vector magnitude function. Sometime, is returns a "not a number"... Is there any easy way to get the area? Thanks!

Calculating magnitude of that vector gives the area of the face. This area vector approach is extremely helpful vector calculations and number crunching. Area = NV_MAG(area_vec); Understand the mathematics than.. criticizing it. Fluent package is developed with strong math and physics oriented approach. -Mubasshir
