part modify fe_part initial_velocity

Allows you to create initial velocities on an existing FE Part.

Translational velocities are specified by parameters VX, VY, and VZ.

Rotational velocities are specified by parameters WX, WY, and WZ.

Note:

The initial translational and rotational velocities are with respect to the FE Part's local reference frame axis or if specified, the vm or wm reference frame axis.

Format:

part modify fe_part initial_velocity
fe_part_name =	existing fe part
vm =	existing marker
wm =	existing marker
vx =	velocity
vy =	velocity
vz =	velocity
wx =	angular_vel
wy =	angular_vel
wz =	angular_vel

Example:

part modify fe_part initial_velocity &
fe_part_name =	FE_Part_2 &
vm =	Marker_14 &
vx =	200 &

This will apply a translational velocity of 200 in modeling units to ALL existing nodes on the FE_Part_2 along the x-axis of Marker_14.

Description:

Parameter	Value Type	Description
fe_part_name	Existing fe part	Specifies the name of the fe part (required)
vm	Existing marker	Specifies a marker about whose axes the translational velocity vector components will be specified (optional). Default reference frame is FE Part’s local part reference frame.
wm	Existing marker	Specifies a marker about whose axes the angular velocity vector components will be specified (optional). If wm is not specified, the reference frame for the initial angular velocities is the FE Part’s local reference frame.
vx	Velocity	Specifies the initial translational velocity of all nodes of FE Part along the x-axis of the FE Part’s LPRF or vm if specified.
vy	Velocity	Specifies the initial translational velocity of all nodes of FE Part along the y-axis of the FE Part’s LPRF or vm if specified.
vz	Velocity	Specifies the initial translational velocity of all nodes of FE Part along the z-axis of the FE Part’s LPRF or vm if specified.
wx	Angular_velocity	Specifies the initial rotational velocity of all nodes of FE Part about the x-axis of the FE Part’s LPRF or wm if specified.
wy	Angular_velocity	Specifies the initial rotational velocity of all nodes of FE Part about the y-axis of the FE Part’s LPRF or wm if specified.
wz	Angular_velocity	Specifies the initial rotational velocity of all nodes of FE Part about the z-axis of the FE Part’s LPRF or wm if specified.

Tip:

1. These arguments will have the same effect of setting the same initial velocities of ALL existing nodes on the given FE Part.

2. For those velocity components not specified, Adams View will set them to zero since Adams Solver requires all six components of velocities to be defined when initial velocities are specified.
