SPDP

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

Format

SPDP(id, jflag, comp, RM)

Example

<Post_Request
     comment = "frc-expr"
     id      = "44"
     type    = "EXPRESSION"
     expr1   = "SPDP(10,0,1, 20)"
     expr2   = "SPDP(10,0,2, 20)"
     expr3   = "SPDP(10,0,3, 20)"
     expr4   = "SPDP(10,0,4, 20)"
     expr5   = "SPDP(10,0,5, 20)"
     expr6   = "SPDP(10,0,6, 20)"
     expr7   = "SPDP(10,0,7, 20)"
     expr8   = "SPDP(10,0,8, 20)"
/>

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

Arguments

id
The ID of the Force_SpringDamper 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.
