Having visited the feko website, I noticed the following bit of news:
*******************************************************
MLFMM for Electrically Large Structures
A new module that will be released with FEKO Suite 4.2 will make the simulation of electrically large structures simpler and a lot faster, requiring dramatically less memory. Whereas the solution of an antenna operating at 1GHz on a military aircraft would require 650 GBytes of RAM using the conventional MoM, the MLFMM can solve the same problem on a single 64bit processor using only 2.5 GBytes of RAM.
The new technology, Multi-Level Fast Multipole Method (MLFMM), is a faster, more efficient method of solving the interaction matrix. The MLFMM has been researched at several research institutions for many years, but FEKO is the first commercial code to bring it to the market for general 3D structures. The MLFMM uses significantly less memory than conventional Method of Moments. For a large class of problems, the entire structure can now be included in the model, and solved without making approximations, or having the limitations usually associated with high frequency techniques. The MLFMM is expected to have the greatest impact on the simulation of electrically large antennas, or antennas mounted on electrically large platforms (e.g. aircraft, ships and automobiles).
********************************************************
According to Feko quarterly, Feko Suite 4.2 will be released in early July.
I wish they added a powerful optimizer module to Feko.
