论文摘要
是由设计用于粒子加速器中超导磁体的淬火保护系统的任务的动机，我们基于磁质质量现场建模来解决一个耦合的场/电路模拟。我们研究Gauß-Seidel类型的波形松弛如何进行耦合模拟时，当使用电路求解套件来描述通过修改的节点分析来描述电路的耦合。我们提出了足够的收敛标准，用于对索引2的差分 - 地球方程（DAE）系统形成的FEM离散的现场模型和电路模型进行耦合模拟。特别是，我们通过简单的基准测试系统证明了电路拓扑对耦合模拟的融合行为的剧烈影响。
Motivated by the task to design quench protection systems for superconducting magnets in particle accelerators we address a coupled field/circuit simulation based on a magneto-quasistatic field modeling. We investigate how a waveform relaxation of Gauß-Seidel type performs for a coupled simulation when circuit solving packages are used that describe the circuit by the modified nodal analysis. We present sufficient convergence criteria for the coupled simulation of FEM discretised field models and circuit models formed by a differential-algebraic equation (DAE) system of index 2. In particular, we demonstrate by a simple benchmark system the drastic influence of the circuit topology on the convergence behavior of the coupled simulation.
