*DEFINE_TABLE_3D

LS-DYNA Input Interface KeywordDefines a 3D table.

Format


(1)	(2)	(3)
*DEFINE_TABLE_3D
`table_ID`	`SCA`	`OFFA`
`A`₁		`Table_ID`₁
`A`₂		`Table_ID`₂
`A`_n		`Table_ID`_n

Definition


Field	Contents	SI Unit Example
`table_ID`	Curve identifier. (Integer)
`SCA`	Scale factor for the value `A`_n. Default = 1 (Real)
`OFFA`	Offset for the value `A`_n. Default = 0 (Real)
`A`_n	Value that corresponds to the following `n`^th curve identifier. (Real)
`Table_ID`_n	Defined 2D table identifier(s). (Integer)

Comments

This keyword maps to /TABLE/1.
The option “_TITLE” can be added to the end of this keyword. When “_TITLE” is included, an extra 80 characters long line is added after the keyword input line which allows an entity title to be defined.
