clump property
command
Syntax
- clump property s a<s1 a1...> <range>
Assign clump or pebble surface properties. The value a is assigned to the surface property with name s. Any number of name-value pairs can be specified.
Note
Pebble properties are surface properties that are used to fill contact model properties. These are distinct from clump attributes (modified with the
clump attribute
command) that are characteristics of clumps, 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.
