SFSF(id, jflag, comp, RM)

Description

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.

Example

<Post_Request

    comment      = "frc-expr"

    id           = "70000044"

    type         = "EXPRESSION"

    expr1        = "SFSF(10,0,1, 20)"

    expr2        = "SFSF(10,0,2, 20)"

    expr3        = "SFSF(10,0,3, 20)"

    expr4        = "SFSF(10,0,4, 20)"

    expr5        = "SFSF(10,0,5, 20)"

    expr6        = "SFSF(10,0,6, 20)"

    expr7        = "SFSF(10,0,7, 20)"

    expr8        = "SFSF(10,0,8, 20)"

/>

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

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 the components are reported. RM=0 implies global frame.
