The BUSH function returns component comp of a force due to BUSHING/id as calculated in the coordinate system of marker rm. If jflag is set to zero, the value returned is the force/torque acting on the I marker of the BUSHING. If jflag is set to 1, the value returned is that acting on the J marker. rm may be specified as zero if the results are desired in the global coordinate system.
Format
BUSH (id, jflag, comp, rm)
Arguments
id | An integer specifying the identification number of the bushing. |
jflag | An integer flag specifying the bushing connectivity marker at which the forces and torques are computed.
0 = forces and moments at the I marker
1 = forces and moment at the J marker |
comp | An integer value that specifies the component of the bushing force to be returned.
1 = Magnitude of the force
2 = x component of the force
3 = y component of the force
4 = z component of the force
5 = Magnitude of the torque
6 = x component of the torque
7 = y component of the torque
8 = z component of the torque |
rm | The coordinate system in which the results are expressed. To return the results in the global coordinate system, set rm = 0. |
Examples
REQUEST/1
, F2=BUSH(1001,0,2,0)/
, F3=BUSH(1001,0,3,0)/
, F4=BUSH(1001,0,4,0)
This REQUEST statement stores the x-, y-, and z-component of the forces in BUSH/1001 in columns 2, 3, and 4, respectively. The forces are calculated at the I marker. The results are computed in the global coordinate system.
