Detailed Description

The Superconvergent Patch Recovery (SPR) nodal recovery model is based on paper of Zienkiewicz and Zhu "The Superconvergent Patch recovery and Posteriori Error Estimates. Part 1: The Recovery Technique", Int.

Journal for Num. Meth in Engng, vol. 33, 1331-1364, 1992. The recovery uses local discrete least square smoothing over an element patch surrounding the particular node considered.
