Detailed Description

The implementation of Zienkiewicz Zhu Error Estimator. The basic task is to evaluate the stress error on associated domain. The algorithm is written in general way, so it is possible to to evaluate different errors (for example temperature error). Then corresponding member attribute identifying the type of quantity used should be declared and initialized (for example in instanciateYourself() service). Then the modification is required only when requesting element contributions.

This task requires the special element algorithms, which are supported at element level using interface concept. This estimator also provides the compatible Remeshing Criteria, which based on error measure will evaluate the required mesh density of a new domain.
