Definition

Field Contents SI Unit Example
OPTION Direction of the acceleration load.
X
Acceleration loading along direction X.
Y
Acceleration loading along direction Y.
Z
Acceleration loading along direction Z.
RX
Centrifugal loading along direction X.
RY
Centrifugal loading along direction Y.
RZ
Centrifugal loading along direction Z.
VECTOR
Acceleration along direction VX, VY, VZ.
LCID Curve identifier for gravity acceleration load as function of time.

(Integer)
SF Scaling coefficient applied to the ordinate of the gravity curve.

Default = 1.0 (Real)
XC, YC, ZC Centrifugal rotational center coordinates. Used only with option RX, RY, RZ.

(Real)

 [ m ]
CID Coordinate system identifier.

(Integer)
VX, VY, VZ Component of the loading direction.

(Real)

Comments

  1. This keyword maps to /GRAV or /LOAD/CENTRI for OPTION = RX, RY or RZ.
  2. The load is to the parts listed in grpart_ID when the card *LOAD_BODY_PARTS is defined in the model. Otherwise, the load is applied on the entire model.
