Abstract

This paper constructed a no matching mesh for neutron transport equations under 2-D cylindrical geometry,and designed a new sweep algorithm and a new method for computing the mesh boundary flows for neutron transport equations on no matching mesh.The new methods can assure the neutron transport equations to be solved successfully using the discontinuous finite element method on no matching mesh.
