Degenerated Whitney prism elements-general nodal and edge shell elements for field computation in thin structures

Nodal and edge shell elements are derived from a degeneration of Whitney prism elements. They can be easily applied to a variational formulation to solve thin structure problems. It is just needed to replace the volume integral by surface integral and the field discontinuity across the thin structure is correctly taken into account. A thin shell eddy current problem is solved using the present elements and dual formulations.
