Method of Moments

In the Method of Moments option, different parameters can be selected to configure the analysis.

Firstly, the user needs to choose the Electromagnetic Equation to solve:

EFIE the Electric Field Integral Equation is considered. This options solves the most of problems and is the most accurate one, but the convergence may be slow or even it may not be achieved in some cases.
MFIE the Magnetic Field Integral Equation is considered. This option provides valid results only for closed bodies, whenever the normal vectors of the geometry is pointing to the proper direction (outside the objects).
CFIE the Combined Field Integral Equation is considered. It is also recommended only for closed bodies, whenever the normal vectors of the geometry is pointing to the proper direction (outside the objects), and it uses a weighted combination of the two previous methods. The CFIE parameter must be defined between 0 and 1, and it weigths the rate in which the EFIE is considered. A value close to 1 is recommended for this parameter to ensure accurate results provided by the EFIE solution, but with the benefits of speeding-up the iterative process with the MFIE formulation (0.8 or 0.9, for example). The CFIE solution combines the two previous methods according to the next formula: CFIE = EFIE · CFIEparameter + (1 - CFIEparameter) · MFIE
