Define Berm Properties

To access the Berm Properties Library, select Berm > Define Berm Properties

This will open the Berm Material Dialog, which allows the user to add/remove berm materials and edit berm material properties. Material properties can be assigned to the model using the Assign Berm Materials option. Aesthetic changes including berm fill colour, hatch pattern, and hatch colour can be selected.

It is necessary for the user to specify if the model will calculate impacts (Calculate Impact) with the berm or if the berm should be assigned an infinite capacity (Infinite Capacity).

• If “Calculate Impact” is selected, impacts are calculated and rocks can bounce off the berm or slide/roll on the berm. The user must input the coefficients of restitution and frictional coefficients, similar to slope materials.
• If “Infinite Capacity” is selected, the berm behaves like a multi-segmented barrier with infinite capacity. The simulation ends when the rock’s center of mass location meets the berm.
