A LOCAL FIELD ERROR PROBLEM APPROACH FOR ERROR ESTIMATION IN FINITE-ELEMENT ANALYSIS

A procedure for the estimation of field errors in finite element analysis, based on a "local" approach is presented. The error estimate is numerically computed over each element solving a problem formulated in terms of field according to Helmholtz's theorem. For the numerical solution of the problem an edge elements approach was used. In the paper the proposed method and the numerical techniques used are described and some comparisons with other known methods are reported.
