The resource requirements (time and memory) for the MLFMM solution are notably smaller than for the full MoM solution. The resource requirements for this example is reduced by using the CFIE formulation on the closed PEC structure of the helicopter. The CFIE required 30% less memory resources and 50% less simulation time for this example when comparing with the default EFIE solution. Some solution times from the .out file are given below. Note that times are dependent on the hardware.
