Computes the length-based average of the variable or expression
on the specified line. This is the 1D equivalent of the areaAve function. The results is independent of the nodal
distribution along the line because a weighting function assigns a
higher weighting to areas of sparse nodal density.
lengthAve(<Variable|Expression>)@<Location>
where:
<Variable|Expression>is a variable or expression.<Location>is any 1D or 2D location.
lengthAve(T)@Polyline1 calculates
the average temperature on Polyline1 weighted
by the distance between each point (T is the
system variable for temperature).
