Hp-FEM Automatic-Mesh Adaptivity Applied to Two Dimensional Neutron Diffusion

摘要

This paper presents an analysis of /z/?-adaptivity applied to the multigroup diffusion criticality problem. The /z/j-adaptive method refines both in mesh size and polynomial order in a competing fashion to locally optimize the refinement scheme [1], whereas the majority of mesh adapting methods improve the solution by either refining the domain space or increasing the polynomial order.
