Relevance to standards
The FSV method is part of the (currently draft)
IEEE standard on “Validation of computational electromagnetics (CEM) for
computer modelling and simulation”.
These are IEEE Projects P1597.1 and P1597.2

The following is an introduction to the standards project.
The Chair and Vice-Chair for this project are Andy Drozd and Bruce Archambeault.
The development of standards and recommended practices for computational electromagnetics (CEM) computer modeling and simulation and code validation has been a topic of much interest within the electromagnetics (EM) community primarily since the mid 1980s. This has been due to advancements in computer hardware and software technologies as well as the arrival of new CEM codes and applications as we know them today. The areas of concern include, but are not limited to analyzing printed circuit board radiated and conducted emissions/immunity, system-level EMC, radar cross section (RCS) of complex structures, and the simulation of various electromagnetic environment effects (E3) problems. In particular, there are concerns regarding the lack of well-defined methodologies to achieve code-to-code or even simulation-to-measurement validations within a consistent level of accuracy.
The scope of P1597.1 is to develop a standard for the validation of CEM computer modeling and simulation (M&S) techniques and codes in differing electromagnetic compatibility (EMC) applications. The standard will provide a basis for analytical and empirical validation of CEM codes and configurations focusing on several key areas, which include:
Validation by use of canonical models – This
refers to the specification of canonical modeling elements as a function of
ensemble parameters (frequency, desired accuracy or fidelity, physics and
numerical solution method, etc.).
Validation by simulation versus measurement -
Includes considerations for model- versus measurement-driven uncertainty
estimates and relationships.
P1597.1 is intended to guide the validation of CEM application models by developing a methodology that will assist in achieving code-to-code or simulation-to-measurement validations within a consistent level of accuracy. The proposed standard is anticipated to provide a method for validating CEM techniques, codes, and models across a range of applications and problem categories. This shall include various EM phenomena and effects such as scattering, RCS, antenna radiation, and high-intensity radiated field environments.
Comparable work has been accomplished and continues to mature on behalf of other collaborative engineering disciplines such as computational fluid dynamics (CFD), thermal and structural/mechanical engineering. These have been referenced for guidance in the development of a draft standard and recommended practice.
The scope of the P1597.2 project is to develop a recommended practice for use in CEM computer modeling and simulation (M&S) applications to guide the electromagnetic compatibility (EMC) design of printed circuit boards to large, complex systems. Areas to be addressed include:
General guidelines for creating CEM models.
Development of modeling methodologies for
small-to-large scale “canonical, standard validation, and benchmark problems.
Reducing uncertainty and errors in modeling
applications.
Developing fundamental modeling techniques that
are consistent with collaborative, multi-disciplinary engineering applications.
The recommended practice will aid
modelers and analysts in the selection and application of appropriate M&S
methodologies, physics, and solution techniques to achieve accurate results and
to complement measurements and EMC design tasks for a range of progressively
complex problems.
