*MODEL CHANGE: Remove or reactivate elements and contact pairs.
This option is used to remove or reactivate elements or contact pairs during an analysis.
Products: Abaqus/Standard Abaqus/CAE
Type: History data
Level: Step
Abaqus/CAE: Interaction module
References:
• “Element and contact pair removal and reactivation,” Section 11.2.1 of the Abaqus Analysis User’s
Manual
• “Removing and reactivating contact pairs” in “Defining contact pairs in Abaqus/Standard,”
Section 34.3.1 of the Abaqus Analysis User’s Manual
Required, mutually exclusive parameters:
ACTIVATE
Include this parameter in any step during an analysis to indicate that elements or contact pairs may
need to be removed or added during a subsequent restart analysis.
ADD
Include this parameter to indicate that the elements or contact pairs involved are being reactivated
during the step.
Set ADD=STRAIN FREE (or include the ADD parameter without a value) to specify strainfree
reactivation for stress/displacement elements or to reactivate other elements or contact pairs.
Set ADD=WITH STRAIN to specify that stress/displacement elements are reactivated with
strain. This option is not relevant for contact pairs.
REMOVE
Include this parameter to indicate that the elements or contact pairs involved are being removed
during the step.
Optional parameter:
TYPE
This parameter can be used only with the parameters ADD or REMOVE.
Set TYPE=ELEMENT (default) to remove or reactivate elements. Set TYPE=CONTACT
PAIR to remove or reactivate contact pairs.
Data lines to remove/reactivate elements (TYPE=ELEMENT):
First line:
1. Give a list of element numbers and/or element set names that are involved in the removal or
reactivation.
Repeat this data line as often as necessary.
Data lines to remove/reactivate contact pairs (TYPE=CONTACT PAIR):
First line:
1. Slave surface name used in the contact pair being removed or reactivated.
2. Master surface name used in the contact pair being removed or reactivated. For self-contact
the master surface name is omitted or is the same as the slave surface name.
Repeat this data line as often as necessary.
No data lines are used with this option when the ACTIVATE parameter is included.
