The hydromagnetic stability of a cylindrical pinch of rectangular cross section is studied numerically using the finite element method. The plasma is subdivided into a number of rectangular elements within each of which the perturbations are expressed in terms of nodal values which are taken as parameters of a Lagrangian. Minimizing the Lagrangian with respect to these variables produces an eigenvalue problem. The stability of the pinch is determined from the eigenvalues. Author
