Manufactured Solutions for the Method-of-Moments Implementation of the Electric-Field Integral Equation
Brian A. Freno, Neil R. Matula, William A. Johnson
Though the method-of-moments implementation of the electric-field integral equation plays an important role in computational electromagnetics, it provides many code-verification ch…
Code-Verification Techniques for Hypersonic Reacting Flows in Thermochemical Nonequilibrium
Brian A. Freno, Brian R. Carnes, V. Gregory Weirs
The study of hypersonic flows and their underlying aerothermochemical reactions is particularly important in the design and analysis of vehicles exiting and reentering Earth's atmo…
Characterization and Integration of the Singular Test Integrals in the Method-of-Moments Implementation of the Electric-Field Integral Equation
Brian A. Freno, William A. Johnson, Brian F. Zinser +3
In this paper, we characterize the logarithmic singularities arising in the method of moments from the Green's function in integrals over the test domain, and we use two approaches…
Symmetric Triangle Quadrature Rules for Arbitrary Functions
Brian A. Freno, William A. Johnson, Brian F. Zinser +1
Despite extensive research on symmetric polynomial quadrature rules for triangles, as well as approaches to their calculation, few studies have focused on non-polynomial functions,…
