4.5 Internal boundaries can be maintained during extruding, revolving, and lofting

Product: ABAQUS/CAE

Benefits: Maintaining internal boundaries can result in regions that can be structured or swept meshed without having to resort to partitioning.

Description: When you are adding an extruded, revolved, or lofted solid or shell feature in the Part module, ABAQUS/CAE allows you to maintain any faces or edges that are generated between the new feature and the existing part. In addition, you can use the Feature Manipulation toolset to maintain the internal boundaries after you have added a swept solid or shell feature.

Previous versions of ABAQUS/CAE merged the new feature with the existing part; for example, a new extruded solid was merged with the cells of the original part. If you choose to maintain the internal boundaries with ABAQUS Version 6.6, the new extruded solid will be separate from the cells of the original part. For example, the part on the left in Figure 4–5 was created without maintaining the internal boundary between the cube and the extruded flange. The part on the right was created with the internal boundary maintained.
