The PTCV function returns component comp of a force due to PTCV/id as calculated in the coordinate system of marker rm. If jflag is set to zero, the value returned is the force acting on the I marker of the PTCV. If jflag is set to one, the value returned is that acting on the JFLOAT marker. rm may be specified as zero if the results are desired in the global coordinate system.
Format
PTCV (id, jflag, comp, rm)
Arguments
id | An integer specifying the identification number of the point-to-curve constraint. |
jflag | An integer flag specifying the point-to-curve 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 point-to-curve constraint 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=PTCV(31,0,2,0)/
, F3=PTCV(31,0,3,0)/
, F4=PTCV(31,0,4,0)/
, F5=PTCV(31,0,5,0)/
, F6=PTCV(31,0,6,0)/
, F7=PTCV(31,0,7,0)/
, F8=PTCV(31,0,8,0)/
This REQUEST statement outputs the x-, y-, and z-components of the force and torque at the I marker of PTCV/31. Since rm is specified as zero, all vectors are expressed in the global coordinate system.
