Description

The linear tearing mode stability is evaluated for 1D equilibria in cylindrical geometry with arbitrary current profiles. This treatment combines the energy method and the Ritz-Galerkin procedure using finite elements. Particularly for hollow currents with two singular q surfaces extremely accurate results showing the coupling influence of both singularities are obtained. (author)
