LOAD_GRAVITY

Loads

*LOAD_GRAVITY
"Optional title"
direc, cid, addmass, csysid, $sf$

Parameter definition

Variable
Description
direc
Direction for gravity loading
options: X, Y, Z
cid
ID of a CURVE or FUNCTION defining gravity coefficient versus time
addmass
Exclude added mass due to mass scaling from gravity loading
options:
0 $\rightarrow$ include added mass
1 $\rightarrow$ exclude added mass
csysid
Optional local coordinate system ID
$sf$
Optional gravity scale factor
default: 1

Description

Defines gravity loading that acts on the full model.

Note: A positive gravity constant results in body forces acting in the negative coordinate axis direction.

Example
