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.

initRegionMap()

void oofem::ZZNodalRecoveryModel::initRegionMap ( IntArray & regionMap, InternalStateType type )

private

Initializes the region table indicating regions to skip.

Parameters

regionMap	Region table, the nonzero entry for region indicates region to skip due to unsupported elements or incompatible value size.
type	Determines the type of internal variable to be recovered.
