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.
