In the present paper, we discuss the accuracy improvement for the free mesh method: a node based finite element technique. We propose here a scheme where the strain field is defined over clustered local elements in addition to the standard finite element displacement field. In order to determine the unknown parameter, the least square method or the Hellinger-Reissner Principle is employed. Through some bench mark examples, the proposed technique has shown excellent performances.
