| Abstract: | D compressible flow of contamination from nuclear waste in porous media is described by a nonlinear coupled partial differential system.Considering the higher computing and storage requirements to evaluate the approximate solution of the large mutidimensional problem,an alternating direction finite element procedure which is based on patches of finite element is considered.With the procdure,a three dimensional problem can be solved as a series of one dimensional problems.Optimal order H 1 error estimates are derived. |
