Multipoint Force (NFORCE)

Returns a force or torque applied by a specified multipoint force on one or two bodies directly affected by the multipoint force.

 

Note:

NFORCE can only be used for output purposes. Therefore, it can be used only with output request and sensor objects.

Format

NFORCE (Multipoint Force Name, At This Marker, Force Component, Along/About Axes)

Arguments

 

Multipoint Force Name	(Required) Multipoint force for which the force is measured.
At This Marker	(Required) Marker on which the force is measured. The legal values are: • 0 = forces and torques on the I marker • 1 = forces and torques on the J marker
Force Component	(Required) Force or torque component you want to measure. The legal values are: • Fm = 1 = force magnitude • Fx = 2 = x component of the force • Fy = 3 = y component of the force • Fz = 4 = z component of the force • Tm = 5 = torque magnitude • Tx = 6 = x component of the torque • Ty = 7 = y component of the torque • Tz = 8 = z component of the torque
Along/About Axes	(Optional) Coordinate system marker in which the results are measured. To have your results measured in the global coordinate system, do one of the following: • If you're entering your function through the Assist dialog box, leave the Along/About Axes text box empty. • If you're entering your function directly in the function text box, enter a 0.

The following function returns the y component of the force vector acting on the second body (at the J marker) of .model_3.nforce_41, measured along the y-axis of .model_3.part_5.marker_3:

NFORCE(.model_3.nfo_5, 1, 3, .model_3.part_5.marker_3)
