Models of such spiral inductors can become quite large as the number of turns increases. This example demonstrates how to exploit the near-symmetry of the structure to greatly reduce the model size. A ten-turn octagonal spiral coil is modeled via the usage of a Single Turn Coil boundary condition, with Floating Potential boundary conditions to enforce continuity of the current between the disjoint turns of the coil.
