Recently, a novel code for the simulation of the plasma equilibrium and its evolution has been developed and fully implemented in ANSYS. We named it ANSYS Plasma Equilibrium and Evolution Code (APEC). It is based on the solution of the Grad–Shafranov equation and exploits the finite-element method using the magnetic potential vector formulation. In this article, we present a further development on the coupling of the axisymmetric plasma equilibrium equations, describing the plasma behavior, with the full 3-D eddy current equations, defining the surrounding 3-D structures. One test case, related to the International Thermonuclear Experimental Reactor (ITER) tokamak, has been fully analyzed and benchmarked with a validated code showing the validity of the proposed approach. In particular, the benchmark has concerned the comparison of the initial equilibrium and plasma evolution.

用于模拟存在 3D 被动结构的等离子体平衡和演化的 APEC 代码的引入和验证

最近，一种用于模拟等离子体平衡及其演化的新代码已在 ANSYS 中开发并完全实现。我们将其命名为 ANSYS Plasma Equilibrium and Evolution Code (APEC)。它基于 Grad-Shafranov 方程的解，并利用使用磁势矢量公式的有限元方法。在本文中，我们展示了轴对称等离子体平衡方程耦合的进一步发展，描述了等离子体行为，以及完整的 3-D 涡流方程，定义了周围的 3-D 结构。一个与国际热核实验反应堆 (ITER) 托卡马克相关的测试案例已经过全面分析，并使用经过验证的代码进行了基准测试，显示了所提议方法的有效性。特别是，
