JOINT

This function returns the specified component of the force or torque due to the Constraint_Joint element.

Format

JOINT(id, jflag, comp, RM)

Arguments

id

The ID of the Constraint_Joint element.

jflag

jflag equal to 0 or 1 means that forces and moments are reported at the I or J marker, respectively.

comp

1: returns the force magnitude.
2: returns the force x component.
3: returns the force y component.
4: returns the force z component.
5: returns the torque magnitude.
6: returns the torque x component.
7: returns the torque y component.
8: returns the torque z component.

RM

The reference frame in which the components are reported.

RM=0 implies the global frame.
