SFSF

Returns force component due to Constraint_SFSF element in reference frame of marker RM. jflag indicates whether force acting on I or J marker is desired.

Format

SFSF(id, jflag, comp, RM)

Arguments

id
The ID of the Constraint_SFSF element.
jflag
0 returns force acting on I marker.
1 returns force acting on J marker.
component
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.

Example

This request element stores the SFSF element forces into column vectors F1 through F8 of the request "frc-expr".
