Fracture

Contains all crack definitions within a model. Supported crack types include:

The application internally generates a mesh for all of the above crack types except for the Pre-Meshed Crack. You import the Pre-Meshed Crack and its mesh from an external source. Furthermore, except for the Arbitrary Crack and the Pre-Meshed Crack, the above crack types are defined as analytical cracks.

Object Properties

The Fracture object has only one category, Definition, and property, Re-mesh Hex-dominant to Tetrahedral. Options include On and Off (default). This property works in combination with the context (right-click) menu option Generate All Crack Meshes. When you turn this property On and then select Generate All Crack Meshes, the application automatically remeshes the body/bodies scoped to any existing Arbitrary Crack or any analytical crack object(s) from a hex-dominant base mesh to a tetrahedral mesh. In addition, for these objects, it will generate the initial crack mesh based on the scoping of the crack surface.

Also note the following:

Because all cracks, except the Pre-Meshed Crack, only support a tetrahedral-based mesh, you must set this property to Onand select the Generate All Crack Meshes option if your fracture analysis includes a crack scoped to bodies that have a hex-dominant base mesh.
For a Multibody Assembly geometry, only crack-scoped bodies get remeshed, but for a Multibody Part geometry, all shared bodies get remeshed.

Tree Dependencies

Valid Parent Tree Object: Model.
Valid Child Tree Objects: Arbitrary Crack, Semi-Elliptical Crack, Elliptical Crack, Ring Crack, Corner Crack, Edge Crack, Through Crack, Cylindrical Crack, Pre-Meshed Crack, Crack Initiation, SMART Crack Growth, Interface Delamination, and Contact Debonding.

Insertion Methods

Select the Model object and select Fracture from the Define group on the Model Context tab.
Right-click the Model object and select Insert > Fracture.

Note:

The Model object supports one Fracture object only.
You need to regenerate the base mesh for all bodies if you delete a Fracture object that includes cracks (analytical or an Arbitrary Crack) for which the application internally generates crack meshes.
