Framework Requirements Traceability Matrix

Introduction

Minimum System Requirements

In general, the following is required for MOOSE-based development:

A POSIX compliant Unix-like operating system. This includes any modern Linux-based operating system (e.g., Ubuntu, Fedora, Rocky, etc.), or a Macintosh machine running either of the last two MacOS releases.

Hardware	Information
CPU Architecture	x86_64, ARM (Apple Silicon)
Memory	8 GB (16 GBs for debug compilation)
Disk Space	30GB

Libraries	Version / Information
GCC	8.5.0 - 12.2.1
LLVM/Clang	10.0.1 - 16.0.6
Intel (ICC/ICX)	Not supported at this time
Python	3.7 - 3.11
Python Packages	packaging pyaml jinja2

System Purpose

The MOOSE Electromagnetics module provides an interface to and library containing Maxwell's equations within the MOOSE application ecosystem. It is intended to be used as either a standalone simulation code for electrodynamics or coupled to other MOOSE ecosystem codes (including MOOSE-wrapped applications). Thus, the Electromagnetics module uses the same object-oriented design as MOOSE in order to make simulation design and new development straightforward for engineers and researchers.

System Scope

The scope of the Electromagnetics module is to provide a set of interfaces and objects for building electrodynamics simulations based on the finite element method (FEM). Regarding solvers, meshing libraries, as well as solution/coupling methods and interfaces, the Electromagnetics module relies on the infrastructure provided by the MOOSE framework.

The system contains, generally, a base set of kernels, boundary conditions, and interface conditions designed for the solution of vector fields derived from Maxwell's equations. Further, it currently contains more specific capability in the following general areas:

Wave reflection, transmission, and absorption
Electrostatic contact on electrically imperfect surfaces

Electromagnetics module developers work with framework and other module and application developers to ensure that the Electromagnetics module provides adequate capability to support on-going and prospective research opportunities involving aspects of electromagnetics.

Assumptions and Dependencies

The Electromagnetics module is developed using MOOSE and can itself be based on various MOOSE modules, as such the RTM for the Electromagnetics module is dependent upon the files listed at the beginning of this document.

Pre-test Instructions/Environment/Setup

Ideally all testing should be performed on a clean test machine following one of the supported configurations setup by the test system engineer. Testing may be performed on local workstations and cluster systems containing supported operating systems.

The repository should be clean prior to building and testing. When using "git" this can be done by doing a force clean in the main repository and each one of the submodules:


git clean -xfd
git submodule foreach 'git clean -xfd'

All tests must pass in accordance with the type of test being performed. This list can be found in the Software Test Plan.

Changelog Issue Revisions

Errors in changelog references can sometimes occur as a result of typos or conversion errors. If any need to be noted by the development team, they will be noted here.

The changelog for all code residing in the MOOSE repository is located in the MOOSE RTM.
