Consistent P1 Synthetic Acceleration of Inner Transport Iterations in 3D Geometry
For the KP1 iterative transport method the production procedure of its “P1” step consistent with an arbitrary spatial approximation of the SN transport equation in 3D Cartesian geometry is presented. The procedure is applied to the nodal schemes approximating the within-group SN transport equation on the unstructured tetrahedral mesh. Produced P1 synthetic accelerations are experimentally shown to be numerically effective on several model problems.
