FORCE

Bulk Data Entry

FORCE – Point Force

Description

Defines a static force at a grid point by specifying a vector. It can also be used to define the EXCITEID field (Amplitude “A”) of dynamic loads in RLOAD1, RLOAD2, TLOAD1 and TLOAD2 bulk data entries.

Format

(1)	(2)	(3)	(4)	(5)	(6)	(7)	(8)	(9)	(10)
FORCE	SID	G	CID	F	N1	N2	N3

(1)	(2)	(3)	(4)	(5)	(6)	(7)	(8)	(9)	(10)
FORCE	2	5	6	2.9	0.0	1.0	0.0

Field	Contents
SID	Load set identification number. (Integer > 0)
G	Grid point identification number. (Integer > 0 or <PartName.number>) See comment 1.
CID	Coordinate system identification number. A CID of zero or blank references the basic coordinate system. Default = 0 (Integer > 0, or blank)
F	Scale factor. (Real)
N1,N2,N3	Components of vector measured in coordinate system defined by CID. (Real; must have at least one non-zero component)

Comments

1.	The static force applied to grid point G is given by:

where, is the vector defined in fields 6, 7, and 8.

Supported local entries in specific parts can be referenced by the use of “fully qualified references” on FORCE entries in the model. A fully qualified reference (“PartName.number”) is similar to the format of a numeric reference. “PartName” is the name of the part that contains the referenced local entry (part names are defined on the BEGIN Bulk Data Entry in the model). “number” is the identification number of a referenced local entry in the part “PartName”. See Parts and Instances in the User’s Guide for detailed information on the use of fully qualified references.
