Development of a Space-time Finite Element Formulation for fast AC Loss Calculation in High Temperature Superconductors

The intern will develop a new space-time finite element formulation to solve steady state problems involving high temperature superconductors in order to evaluate rapidly the losses in a given application. This space-time formulation will also be coupled to a mesh adaption program used to refine the solution only where it is really necessary. This formulation is expected to be advantageous over current formulation since it will avoid using very fine spatial and geometric discretization in the entire simulated domain. If this project completes successfully, it will provide a new and powerful tool to optimize the design of high temperature superconducting wires and applications. Such optimization tools are the key to economically-competitive applications, such as power transformers and generators.
