Add Weak Layer

A Weak Layer boundary allows you to define a polyline boundary with strength properties, which can be used to model joints or interfaces (for example) along which sliding might occur.

To add a Weak Layer boundary to your model:

1. Select Add Weak Layer from the toolbar or the Boundaries menu.
2. Enter the vertices of the boundary as described in Entering Coordinates.
3. When all vertices are entered, right-click and select Done, or press Enter with nothing in the prompt line.
4. A dialog will appear which allows you to assign material properties to the weak layer. Select a property and select OK.
