Assign properties to liner elements in the range. The properties consist of constitutive model properties, beam-type properties, and coupling-spring properties. The constitutive model property names are primary keywords, but are not included in the list above. The following properties are available, with the constitutive model properties listed first.

Beam Constitutive Model Properties

All liner constitutive models have properties associated with them. Properties are name value pairs, where the name is the keyword given in the command and the value type is specific to the property. The assignment will affect any beam-type element in the specified range whose constitutive model includes the property named (noting that some properties, such as young, appear in multiple liner constitutive models). There is one liner constitutive model.
