Performing accurate simulations of large- and multi-scale electromagnetics problems has far-reaching implications in a variety of engineering and scientific disciplines. The same physics governs a diversity of applications including problems of importance for NAVAIR such as complex radome-antenna and antenna-platform interactions.  Such simulation problems involve complex materials, multiple feeds and loads, multiscale meshing challenges, and geometries that may exceed 1000 wavelengths in one or more dimensions. Unfortunately, the typical workflow of computational electromagnetics (CEM) has not changed in 40 years.  Typically, meshes are created based on some user knowledge of the underlying problem and likely are limited to low-order polynomial elements.  Polynomial mesh generation contributes to two issues: limited accuracy of the geometry representation and large linear systems. IERUS Technologies proposes a radical departure from the standard workflow that has bogged down high accuracy CEM analysis since its inception: eliminate meshing altogether as it is currently known.  To achieve this, the team will transition so-called “analysis-suitable” spline technology to CEM solvers through a method known as isogeometric analysis (IGA) or spline-based simulation.  IERUS will transition this technology to our commercial solver V-Lox to obtain geometry-perfect, high-order accurate solutions for large-scale CEM problems.
