Detailed Description

The nodal recovery model based on paper of Zienkiewicz and Zhu "A Simple Estimator and Adaptive Procedure for Practical Engineering Analysis".

The recovery is based on nodal averaging or projection process in which it is assumed that the stress $\sigma_\star$ is interpolated by the same function as the displacement.
