ball property command


ball property s a<s1 a21...> <range>

Assign ball surface properties. The value a is assigned to the surface property with name s. Any number of name-value pairs can be specified.


Ball properties are surface properties that may be used to fill contact model properties. These are distinct from ball attributes (modified with the ball attribute command) that are characteristics of balls such as position or size.

The list of mechanical contact models is given in the “Contact Models” section. In the documentation for each contact model, a Properties table exists. These include: the linear, linear contact bond, linear parallel bond, hertz, hysteretic, smooth joint, and the flat joint property tables.

Usage Example

Be aware of the distinction between attributes and properties! The tutorial example “Attributes and Properties” discusses this issue in detail.
