Progress in the development of an automatic, self-adaptive, two-dimensional finite element technique, whose basic philosophy has been reported previously, is presented. The procedure involves the following steps: (1) generation of an array of nodes according to a nodal density function; (2) construction of a triangular mesh from the nodal array, and (3) modification of the nodal density function in light of the finite element solution. The various algorithms that have been used to execute these steps are discussed, and the performance of the technique on a trial problem containing a stress singularity is reported.
