Field

Contents

SID

Load set identification number.

No default (Integer > 0)

G

Grid point identification number through which the rotation vector acts.

Default = 0 (Integer > 0)

CID

Coordinate system defining the components of the rotation vector.

Default = 0 (Integer > 0)

A

Scale factor of the rotational velocity in revolutions per unit time.

Default = 0.0 (Real)

R1,R2,R3

Rectangular components of rotation direction vector. The vector defined will pass through point G.

RACC

Scale factor of the rotational acceleration in revolutions per unit time squared.

(Real)

Comments

  1. G = 0 or blank means the basic coordinate system origin.

  2. CID = 0 or blank signifies that the rotation vector acts at the origin of the basic coordinate system.

  3. The RFORCE load is selected for use in a subcase by the Subcase Information entry LOAD.

  4. The load vector generated by this entry can be printed using the I/O Option OLOAD.

  5. The continuation line containing RACC is optional.
