“…The finite element method (FEM) is widely used for modeling solid-state mechanics [4], flow [3], and magnetodynamic systems, including microwave [9] and magnetoinductive [7] systems. Recently developed open-source FEM-based toolchains give the unprecedented possibility of flexible modeling and development of advanced and sophisticated systems, such as eddy current tomography [8], resistive tomography [6,11], or airplane mechanics optimization [13].…”

Tetrahedral meshing is the critical element of finite element modeling. Recently, adaptive meshing has been commonly used. In such meshing, according to the Delaunay method, mesh density is connected with the curvature of modeled object’s edge. Such a method is especially efficient during the modeling of mechanical systems. However, the efficiency of commonly used meshing algorithms is strongly limited in surface-focused phenomena, such as eddy current induced by magneto-dynamic processes. The paper proposes the improved method of Delaunay meshing considering the specific requirements of magnetodynamic systems. In the proposed method, tetrahedral mesh density may be flexibly modified according to the needs of modeled physical phenomena, such as eddy current density. As a result, physical effects may be efficiently and accurately described in finite element models. The paper presents the example of implementing the proposed solution for cylindrical wire. The complete source code is available as open-source software for further practical use and development.

“…The health implications of air ionization have been reviewed elsewhere [1]- [5]. Improved diagnostics and mechanistic understandings of electrical discharges in gases [6]- [7] have led to the development of engineered devices with highly controllable processes for the generation of non-thermal plasmas in the treatment of chemical [8], [26], [27] and biological contaminants [9]- [12]. Coupled with the increased interest in controlling the potpourri of airborne contaminants, there has been an awakening kindled in applying this technology for improving the air quality of enclosed indoor environments [13]- [17].…”
