摘要
The spiral coil made of thin coated conducting tape is substituted by a homogenized bulk medium for the finite element simulation of its electromagnetic behavior. The homogenized medium is represented by an anisotropic conductivity tensor utilizing the underlying spiral structure. In addition to the significant reduction of the computational efforts, the method notably makes voltage on the coil terminals directly available in context of the A-V potential formulation. The main application is the simulation of large high-temperature superconducting coils, but any other devices with rolled foil conductor may be tackled similarly. In this work a feasibility study and simulation of the critical state are performed by means of a test problem.
