摘要：
The paper presents a simple and practical method for the local error assessment in the finite element solution of fields in linear media governed by the Laplace equation. The local error is estimated for each node or element of the mesh model by applying the Green integration formula, with the error distribution being used for the adaptive mesh refinement. Several alternatives of the local error estimation algorithm are compared and numerical examples are given for a typical 'L'-section potential problem. These confirm the efficiency of the proposed method.
