Description: Abaqus/CAE now allows you to edit and remove attachment features, specify the connectivity of surfaces for point-based fasteners, and import discrete fasteners from an input file written from Abaqus/CAE. In addition, you can now suppress and resume fasteners. For more information on suppression of attributes, see “Enhancements to suppression of attributes in Abaqus/CAE,” Section 4.4.

You can edit attachment points created by choosing a direction and a spacing, points created by patterns based on edges, and lines created by projecting points. You can remove individual attachment points and lines from previously created attachment features. The Remove Attachments feature appears in the Model Tree in the Feature container under the part (if the attachment points were created in the Part module or Property module) or under the assembly (if the attachment features were created in the Assembly module or Interaction module). The Remove Attachments feature can be suppressed, resumed, or deleted.

In the Domain tabbed page of the fastener editor, you can now specify the approach for defining the surfaces of the fastener. You can use the whole model, or you can specify surfaces by either having Abaqus/CAE connect the surfaces by proximity to the positioning points or by specifying the order of the selected surfaces.

When you submit a job that contains a model with discrete fasteners, Abaqus/CAE writes special comment lines to the input file. These special comment lines:

• allow Abaqus/CAE to import the discrete fasteners as originally modeled in Abaqus/CAE;

• immediately precede the Abaqus keywords used to define the discrete fasteners;

• begin with **@ABQCAE; and

• are ignored by the Abaqus solvers.

The graphical symbol used to represent discrete fasteners has been enhanced. For discrete fasteners on model geometry, the radius of the circular symbol is equal to the radius of influence.
