Description: ERATO stability code. Nature of problem: This computer code treats the stability of a Tokamak-like plasma described by the ideal linearized magnetohydrodynamic (MHD) equations. The plasma is considered to be in an equilibrium state. After perturbation of such an equilibrium, the evolution of the normal modes can be calculated by linearizing the ideal MHD equations. Any mode (unstable or stable) of the spectrum can be examined. Solution method: The variational form of the 2D ideal MHD equations is treated by a finite hybrid element approach, which proves to be well suited to describe the features of the problem with sufficient accuracy. The eigenvalue problem Ax= Omega squared Bx is solved by VEKIT (an inverse vector iteration), a subprogram of the block matrix library HYMNIABLOCK. The code consists of 5 main programs (ERATO 1 to ERATO 5) linked together by disk files.
