JPRIM

Returns constraint force component comp associated with Constraint_Jprim with the ID "id", calculated in the reference frame of marker "RM".

Format

JPRIM(id, jflag, comp, RM)

Arguments

id

The ID of the Constraint_Jprim element.

jflag

0 returns force acting on the I marker.

1 returns force acting on the J marker.

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 components are reported. RM=0 implies global frame.
