## Abstract This paper compares three methods for dealing with an exterior boundary value problem by the Finite Element Method, one of which involves using an infinite element. The methods are illustrated by application to the problem of ground water flow round a tunnel with permeable invert. The u

## Abstract Convergence of a finite element procedure for the solution of the fourthβorder equations is proved. A generalization of this result is mentioned and some remarks concerning the numerical results obtained at the Computing Centre of the Technical University in Brno are given.
This paper uses examples with exact solutions to demonstrate that boundary Bows with 8-node finite elements are more cost effectively calculated by extrapolation from the Barlow points than by direct sampling at the boundary. The boundary flows are used to calculate the mass balance, and the use of
In this paper the application of the theorems of structural variation to finite element problems is presented and a simplified procedure for constant strain triangular elements is developed. Applications for these techniques are discussed.
