Application of a SVD-Based Fast Technique for the Analysis of 3D Instabilities of Fusion Plasmas

This paper illustrates the application of a fast SVD-based technique to the analysis of resistive wall modes in fusion devices. The computational cost scales almost linearly with the number of discrete unknowns, allowing the solution of large scale 3D problems of interest for existing or future fusion devices like the International Tokamak Experimental Reactor.
