I would like to access the area value of all the mesh pieces of a boundary face in order to compute the total area of the face. I'm using: F_AREA(A,f,t). My question is: do I need to include it in the "begin_f_loop" or does the macro F_AREA(A,f,t) save automatically all the components? so in C-language: is it like this?:

real Atot=0; F_AREA(A,f,t) begin_f_loop(f,t) { Atot= Atot+NV_MAG(A); }

or like this:

real Atot=0; begin_f_loop(f,t) { F_AREA(A,f,t) Atot= Atot+NV_MAG(A); }

Sorry I forgot the semicolon after F_AREA(A,f,t), so one more time:

real Atot=0; F_AREA(A,f,t); begin_f_loop(f,t) { Atot= Atot+NV_MAG(A); }

or like this:

real Atot=0; begin_f_loop(f,t) { F_AREA(A,f,t); Atot= Atot+NV_MAG(A); }

real Atot=0; begin_f_loop(f,t) { F_AREA(A,f,t); Atot= Atot+NV_MAG(A); } end_f_loop(f,t)
