Detailed Description

template<SizeType TDim>
class Kratos::ContactSPRErrorProcess< TDim >

This class is can be used to compute the metrics of the model part with a superconvergent patch recovery (SPR) approach.

The formulation employed in order to compute the super patch recovery is based on the work of O. C. Zienkiewicz J. Z. Zhu, and extended for contact mechanics. In the papers:

The superconvergent patch recovery and a posteriori error estimates. Part 1: The recovery technique https://onlinelibrary.wiley.com/doi/abs/10.1002/nme.1620330702
The superconvergent patch recovery and a posteriori error estimates. Part 2: Error estimates and adaptivity https://onlinelibrary.wiley.com/doi/abs/10.1002/nme.1620330703 This is a general recovery technique is developed for determining the derivatives (stresses) of the finite element solutions at nodes. The implementation of the recovery technique is simple and cost effective.
Template Parameters

TDim The dimension to be computed
