Abstract
AbstractThis paper presents a general theory and application of the finite element method for some special class of non‐self‐adjoint problems. The formulation employed here is based on the Galerkin method for linear boundary value and eigenvalue problems described by the partial differential equations of elliptic type, and it can be regarded as an extension of the usual displacement method formulated by the use of the principle of minimum potential energy. In order to illustrate its validity and feasibility, the method is applied to the problems of the two‐group neutron diffusion equations and of the stability of a non‐conservative system.
