Volume average

Hi,
I have a question about volume average. If the mesh contains nodes of different sizes is this accounted for in the volume average? (i.e, when calculating average force in a volume, is the result a summation of forces/node size or just the force?)
if there is no division by node area then is it possible to get this information?
thanks

Hi
from my understanding the average in v4 is a shortcut for "intop1(whatever)/intop1(1)" where intop1(1) = volume and means the volume integration of operand "1*dx*dy*dz" (hence the element size is included de facto). In 3.5 one had to write it out like that, it's easier now in V4
for a surface average it's the same, but there the double integration normalisation gives the Area, etc.

Good luck
