DEF_TYPE = SYSTEM

Selection area

EL_GROUP	= `<name_of_element_group>`	Name of an element group in which the value of the design response is to be determined.
ND_GROUP	= `<name_of_node_group>`	Name of a node group in which the value of the design response is to be determined.
ELEM	= `<number_of_element>`	Number of an element to be used for the design response (alternative to `EL_GROUP`).
NODE	= `<number_of_node>`	Number of a node to be used for the design response (alternative to `ND_GROUP`).
CS_REF	= `<coordinate_system>` = CS_0	Default coordinate system is the global coordinate system `CS_0`. Can be used for displacements, internal forces, reaction forces,center of gravity and accelerations.
GROUP_OPER	Operator for determining the design response that is used within the selection area.
	= MAX	Maximum value of the selection area.
	= MIN	Minimum value of the selection area.
	= SUM	Sum of all values of the selection area.
	= COUNT	Determines the number of values of the selection area.

Items for load case dependent design responses

LC_SET combines load cases to determine the value of the design response (can be specified several times). If the LC_SET option is not specified the default setting LC_SET = ALL, ALL, ALL is assumed. It is only available for DEF_TYPE=SYSTEM.

LC_SET = <approach>, <loadcase>, <substep>, <shell_layer>

`<approach>`		Approach / analysis type.
	ALL	All analysis types will be considered.
	STATIC	Static analysis.
	MODAL	Modal analysis.
	NONLINEAR	Non-linear analysis.
	DAMAGE	Durability analysis.
`<loadcase>`		Load case.
	ALL	All load cases will be considered.
	`<no_of_load_case>`	Number of a specific load case.
`<substep>`		Substep.
	ALL	All substeps will be considered.
	`<no_of_substep>`	Number of a specific substep.
`<shell_layer>`		Location for calculation of shell stresses or strains.
	TOP	Top-layer of shell.
	MID	Mid-layer of shell (part of membrane).
	BOT	Bottom layer of shell.
	MAX	Max (`TOP,` `MID`, `BOT`).
	MIN	Min (`TOP`, `MID`, `BOT`).

Tip: For Abaqus users, substep refers to the increment of a nonlinear analysis. Substep does not refer to the load case number in an Abaqus step with multiple load cases.
