The FIELD function returns component comp of a force due to FIELD/id as calculated in the coordinate system of marker rm. If jflag is set to zero, the value that is returned is the force/torque acting on the I marker of the FIELD. If jflag is set to 1, the value that is returned is the value acting on the J marker. For results that are in the global coordinate system, you can specify rm as zero.
Format
FIELD (id, jflag, comp, rm)
Arguments
id | An integer specifying the identification number of the FIELD. |
jflag | An integer flag specifying the FIELD 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 FIELD 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=FIELD(1001,0,2,0)/
, F3=FIELD(1001,0,3,0)/
, F4=FIELD(1001,0,4,0)
This REQUEST statement stores the x-, y-, and z-component of the forces in FIELD/1001 in columns 2, 3, and 4, respectively. Adams Solver (C++) calculates the forces at the I marker, and computes results in the global coordinate system.
