Average
An Average nonlocal coupling () computes the average of an expression over the source (some selected geometric entities). It can be evaluated anywhere in the model. It is similar to the Integration operator; the difference being that the integral is divided by the volume, area, arc length, or number of points in the source, depending on the type of geometric entities in the source. The default Operator name is aveop1.
