Abstract

A discrete ordinates method for two-dimensional neutron transport equation based on un-benchmark problems demonstrate that this method can be used in unstructured-meshes and can give high pre-cision result.structured-meshes is derived from the first order neutron transport equation.A set of differential equations about the spatial variables can be obtained.They are solved iteratively by using the least-squares finite ele-ment method.A two-dimensional transport calculation code is encoded.The numerical results of some
