12.12 System Compliance Requests

SYSTEM_COMPLIANCE

SYSTEM_COMPLIANCE step_number = ns, etc...

Compute system compliance starting at step number ns. The system compliance is defined as:

where the global displacement vector d is the solution to the equilibrium problem:

and K = global stiffness matrix of the discretized system.

Note Variable Name Type Default Description

(1) Element_group(s) string [none] Element groups for which computing

compliance is to be performed

Name(s) must be enclosed in

quotation marks

Step_number integer [0] Time step number at which

computing compliance is to be

initiated

Frequency integer [0] Step number frequency at which

computing compliance is to be

performed

EXAMPLE

System_compliance /

step_number = 1 /

frequency = 1 /

element_group(s) = "solid"

Notes /

(1) List all element group names for which the system_compliance is to be recovered.
