Hi.

What is the difference between an average facet value and an average area value?

Cheers Tom

A facet value is evaluated on the face of the cell, an average area weighted value is the average value on the selected surface.

Hi

ap

Thank you for your answer.

The reason for the question is that I have an outlet surface. If I calculate the facet value for the surface and the average value for the surface I do not get the same result. Do you know why there is a difference?

I think it is like this.

Assume all your surface is composed of 3 faces of different area, i.e. 2, 3, 5 M^2.

Assume the variable of your interest in these faces are 12, 15, and 18 Pa (assume pressure)

Then:

Average value based on surface area will be (2*12 +3*15 +5*18)/(2+3+5)

Average facet value will be (12*1 +15*1 +18*1)/(1+1+1) where the number 1 reprents facet.
