"The latest in parallel EM solutions with both in-core and
The solution of complex electromagnetic (EM) problems requires
one to address the issues related with numerical accuracy and
efficient distribution of the solution procedure over multiple
computational nodes. With the advent of multicore processors and
high performance computing (HPC) technology, the EM software
designers need to know how to add new functionality to
computational EM codes so that they can run efficiently on these
"Higher Order Basis Based Integral Equation Solver HOBBIES]"
presents a road map for the analysis of complex material structures
using the high-performance parallel simulation software known as
HOBBIES. Focusing on the Method of Moments (MoM), the book features
new parallel programming techniques and user-friendly code with
superior capabilities for solving challenging EM radiation and
scattering problems. It provides readers with complete guidance on
how to extend the capability of MoM and achieve faster and more
accurate EM analysis and utilize multicore CPUs on desktop
computers. Complete with an academic version of the HOBBIES
software, this book: Explains the unique features of the higher
order basis functions in the solution of integral equations in a
MoM contextShows how to generate a properly load balanced parallel
computational procedure for MoM matrix filling and matrix equation
solving in both in-core and out-of-core implementationPresents a
professional graphical users interface (GUI) for generating the
geometrical structure based on NURBS modelingIllustrates various
automatic meshing procedures based on an a-priori defined error
between the actual geometry and the meshed structureOutlines all
the key features of the HOBBIES software, including multiple
optimization procedures for EM synthesis
The bottleneck of traditional MoM arises from the lack of memory
in computers for solution of large problems. This is mitigated by
using higher order basis functions and out-of-core solver in
HOBBIES. HOBBIES has the capability to perform numerically accurate
EM simulations using thousands of CPU cores in an HPC environment
using a properly load balanced out-of-core solver. In this way, it
provides a cost-effective choice for addressing modern engineering
and scientific challenges that arise from the extremely complicated
