Removing elements and contact pairs (Abaqus)

During an Abaqus structural analysis, you may need to add or remove portions of a structure from the finite element model. Use the Element Removal simulation object to selectively remove elements from one or more steps in the analysis. In subsequent steps, you can use the Element Removal command to reactivate elements, either with or without strain. You can use this simulation object only in General Analysis type steps.

The Element Removal simulation object writes the *MODEL CHANGE keyword to your Abaqus input file.

The ability to deactivate and reactivate elements is useful, for example, for analyzing excavation and construction of tunnels.

For more information, see:

• Element Removal dialog box (Abaqus)

• *MODEL CHANGE in the Abaqus Keywords User’s Guide

• Element and contact pair removal and reactivation in the Abaqus Analysis User’s Guide
