Force: Gravity

Command ElementModifies a gravity force element.

Format

<Force_Gravity
grav_x    = "motionsolve_expression"
grav_y    = "motionsolve_expression"
grav_z    = "motionsolve_expression"
/>

Attributes

grav_x
Defines the acceleration due to gravity in the global X direction. The default value is 0.0.
grav_y
Defines the acceleration due to gravity in the global Y direction. The default value is 0.0.
grav_z
Defines the acceleration due to gravity in the global X direction. The default value is 0.0.

Example

<Force_Gravity
grav_x = "0."
grav_y = "0."
grav_z = "STEP(TIME,0,0,1,-9810)"
/>
