Calculates the volume-weighted average of a variable or expression
on a 3D location. This is the 3D equivalent of the areaAve function. The volume-weighted average is the average value on a
location weighted by the volume assigned to each vertex on a location.
Without the volume weighting function, the average of all the nodal
values would be biased towards values in regions of high mesh density.
The following example demonstrates use of the function.
volumeAve(<Variable|Expression>)@<Location>
where:
<Variable|Expression>is a variable or expression.<Location>is any 3D region (such as a domain or subdomain).
