Any tutorials for HFSS-IE (Moethod of Moment Solver for HFSS) ?

There seem to be several examples in the HFSS user manual and around the web on using HFSS with the default FEM solver based on the PDE form of Maxwell's Equations.

But I can't seem to find much on the use of the optional HFSS-IE, which is based on the Method of Moments and so more suited for electrically large problems.

Does anyone have any useful information about using HFSS-IE they can share?

HFSS IE is based on integral equation,
