Description

We investigate coupling and preconditioning techniques for 1-D hybrid neutronics calculations. Each problem is represented by two spatial regions with Sn used in one region and either diffusion or P3 used in the other. For each of these two cases we define one coupling scheme and two preconditioned systems. These systems are solved with both fixed-point iteration and the GMRES Krylov method. The solution techniques are compared in terms of iteration count and CPU time per iteration. Preconditioning with a global diffusion operator is found to be very effective for the most difficult problems. (authors)
