This paper presents an accurate formulation for the static multi-group neutron transport equation in the three-dimensional geometry. The variational formulation involves the use of a double finite element method, in which the space and angle finite elements are employed. Multilateral prism geometry

Three new fully implicit methods which are based on the (5,5) Crank-Nicolson method, the (5,5) N-H (Noye-Hayman) implicit method and the (9,9) N-H implicit method are developed for solving the heat equation in two dimensional space with non-local boundary conditions. The latter is fourth-order while
We present a 19-point fourth-order finite difference method for the nonlinear second-order system of three-dimensional elliptic equations Au,, + Bu,, + Cu,, = f, where A, B, C, are M X M diagonal matrices, on a cubic region R subject to the Dirichlet boundary conditions u(x, y , z ) = U'~)(X,Y, z )
The perfectly matched layer boundary condition is incorporated into the beam propagation method based on a "nite element scheme for 3-D optical waveguides. Not only an approximate scalar formulation but a full-wave formulation is presented. Its e!ectiveness is veri"ed by way of numerical examples.
