JPRIM(id, jflag, comp, RM)

Description

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

Example

<Post_Request

    comment             = "force on Jack"

    id                  = "9001441"

    type                = "EXPRESSION"

    expr1               = "NULL"

    expr2               = "JPRIM(214001,1,2,21401012)"

    expr3               = "JPRIM(214001,1,3,21401012)"

    expr4               = "JPRIM(214001,1,4,21401012)"

    expr5               = "NULL"

    expr6               = "NULL"

    expr7               = "NULL"

    expr8               = "NULL"

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.
