  • An enhanced flexible time-stepping scheme for the hybrid time-domain finite element method

    This paper presents a flexible time-stepping scheme for the time-domain finite element method (TDFEM) based hybrid field-circuit solver that allows subsystems of different sampling rates to be coupled in time. Because of this flexibility, the proposed time-stepping scheme could significantly improve the computational efficiency of the existing TDFEM-based hybrid field-circuit solver especially when the computational cost associated with the slow subsystems is much larger than that associated with the fast subsystems. Moreover, the efficiency of the hybrid field-circuit simulation with the proposed scheme could be further enhanced when the tree-cotree splitting (TCS) technique is applied to the TDFEM part to reduce the iteration count per time step for a preconditioned iterative solution when the time-step size for the FEM subsystem becomes relatively large.

  • Numerical modeling of PCB power/ground plate-pairs by DGTD method taking into account decoupling capacitors

    A discontinuous Galerkin time-domain (DGTD) method is proposed in this work to analyze printed circuit board (PCB) power/ground plate-pair having arbitrarily shaped anti-pads. To apply proper excitation source over the irregular anti- pad, the implemented wave port magnetic current excitation is expanded by the electric eigen-modes of the anti-pad that are calculated via either numerical approach or analytical method. Based on the orthogonality of eigen-modes, the temporal mode expansion coefficient for each mode can be conveniently extracted. Besides, considering the presence of decoupling capacitors, the whole physical system can be split into field and circuit subsystems. For the field subsystem, it is governed by the Maxwell's equations, thus it will be solved by DGTD method. For the circuit subsystem, the modified nodal analysis (MNA) is applied. In order to achieve the coupling between the field and circuit subsystems, a lumpled port is defined at the interface between the field and circuit subsystems. To verify the proposed algorithm, several representative examples are benchmarked.

  • A Hybrid Electromagnetics-Circuit Simulation Method Exploiting Discontinuous Galerkin Finite Element Time Domain Method

    A hybrid electromagnetics (EM)-circuit simulation method employing the discontinuous Galerkin finite element time domain (DGFETD) method is developed to model single lumped port networks comprised of both linear and non-linear elements. The whole computational domain is split into two subsystems: one is the EM subsystem that is analyzed by DGFETD, while another is the circuit subsystem that is modeled by the Modified Nodal Analysis method to generate a circuit subsystem. The coupling between the EM and circuit subsystems is achieved through a lumped port. Due to the local properties of DGFETD operations, only small coupling matrix equation systems are involved. To handle non-linear devices, the standard Newton-Raphson method is applied to the established non-linear matrix equations. Numerical examples are presented to validate the proposed algorithm.

  • Modeling hybrid EM-circuit system with wave equation-based discontinuous Galerkin time domain method

    In this proceeding, we propose a hybrid solver to model the electromagnetic- circuit problem. The EM subsystem is modeled by wave equation-based discontinuous Galerkin time domain (DGTD-WE) method while the circuit subsystem is computed with a SPICE-like circuit solver. Besides, a stable and general impedance transmission boundary condition (ITBC) is developed to couple the EM and circuit subsystems. Numerical example is presented to demonstrate the validity of the proposed method.

  • Incorporation of frequency-dependent multiport lumped networks into a hybrid time-domain finite-element solver

    This paper presents an accurate and efficient algorithm to incorporate multiport lumped networks into a hybrid field-circuit solver based on the time-domain finite-element method (TDFEM). By casting its admittance matrix into the time-stepping equations, a lumped-network subsystem is formulated and then interfaced with the FEM subsystem through the FEM edges and the circuit subsystem through circuit nodes. The lumped-network port voltages are explicitly set to be the same as those computed from the FEM (or circuit) subsystem while its port currents are used as impressed current excitations along the associated FEM edges (or through the related circuit nodes). Finally, all the lumped-network port variables are eliminated to form a global system for only the FEM and circuit unknowns. The proposed algorithm provides a systematic and efficient scheme for incorporating lumped networks into the TDFEM analysis and thus significant extends the modeling capability and improves the simulation efficiency of the existing hybrid field-circuit solver.

  • A Flexible Time-Stepping Scheme for Hybrid Field-Circuit Simulation Based on the Extended Time-Domain Finite Element Method

    This paper describes a flexible time-stepping scheme for a recently developed hybrid field-circuit solver based on the extended time-domain finite element method (TDFEM) to alleviate the limitation on the use of a system-wide global time-step size. The proposed time-stepping scheme generalizes the strict synchronous coupling mechanism between the FEM and circuit subsystems and allows the signals in the different subsystems to be tracked and sampled at different time-step sizes. The signals from a slow subsystem with a larger time-step size are extrapolated, when necessary, for updating the signals in a fast subsystem with a smaller time-step size. The capability of the hybrid field-circuit solver with the proposed time-stepping scheme is further enhanced by the application of a tree-cotree splitting technique to the FEM subsystem, which helps reduce the iteration count per time step for a preconditioned iterative solution when the time-step size of the FEM subsystem becomes relatively large. With the flexibility of choosing subsystem-specific time-step sizes, the proposed time-stepping scheme improves the computational efficiency of the existing TDFEM-based hybrid field-circuit solver especially when the computational cost associated with the slow subsystems is much higher than that associated with the fast subsystems.

  • Cosimulation of Electromagnetics-Circuit Systems Exploiting DGTD and MNA

    A hybrid electromagnetics (EM)-circuit simulator exploiting the discontinuous Galerkin time domain (DGTD) method and the modified nodal analysis (MNA) algorithm is developed for analyzing hybrid distributive and nonlinear multiport lumped circuit systems. The computational domain is split into two subsystems. One is the EM subsystem that is analyzed by DGTD, while the other is the circuit subsystem that is solved by the MNA method. The coupling between the EM and circuit subsystems is enforced at the lumped port where related field and circuit unknowns are coupled via the use of numerical flux, port voltages, and current sources. Since the spatial operations of DGTD are localized, thanks to the use of numerical flux, coupling matrices between EM and circuit subsystems are small and are directly inverted. To handle nonlinear devices within the circuit subsystem, the standard Newton-Raphson method is applied to the nonlinear coupling matrix system. In addition, a local time-stepping scheme is applied to improve the efficiency of the hybrid solver. Numerical examples including single and multiport linear/nonlinear circuit networks are presented to validate the proposed solver.
