Solution of algebraic problems arising in nuclear reactor core simulations using Jacobi-Davidson and Multigrid methods

Solution of algebraic problems arising in nuclear reactor core simulations using Jacobi-Davidson and Multigrid methods

The solution of large and sparse eigenvalue problems arising from the discretization of the diffusion equation is considered. The multigroup diffusion equation is discretized by means of the Nodal expansion Method (NEM) [9, 10]. A new formulation of the higher order NEM variants revealing the true n...
