This section tests the removal and introduction of elements or contact pairs during the course of an analysis. The problems in this section can be divided into two groups of tests. The first group focuses on a simple uniaxial deformation mode and reintroduction of elements, without strain, in an annealed state. These tests are divided into sections according to the elements that can use the annealed element pair removal capability and by the analysis procedure used in the test. The second group is more general and focuses on the reintroduction of elements both with and without strain and with initial conditions. These tests are divided primarily into sections according to element type but include a number of miscellaneous tests.
The group of more general tests is described in Stress/displacement model change: general tests.
