Reply To: Is there any way to calculate F_AREA,NV_MAG manually?

Hello Karthik Thank you for replying. I mean 'analytically' by the word 'manually' . We can calculate outer surface area of of a tube by 2*pi*r*h which should be same as using 'surface integral'(area). But, I want to know the difference between these(analytical/surface integral(area) area and F_AREA(area,f,tf) ,area_face=NV_MAG(area).
Which area we get when we use the macros F_AREA(area,f,ft) and area_face=NV_MAG(area)?
