The PINVAL function returns component comp of PINPUT/id.
Format
PINVAL (id, comp)
Arguments
id | The identifier of the PINPUT whose data is being requested. |
comp | An integer that specifies the component of the PINPUT to be returned. |
Examples
VARIABLE/21, FUNCTION=10*SIN(2.4*TIME)+3.5
VARIABLE/22, FUNCTION=DZ(21,11,32)
PINPUT/10, VARIABLES=21,22
SFORCE/1, TRANSLATIONAL, I=62, J=47
, FUNCTION=-1.08*(PINVAL(10,2)-4.6)
PINPUTs and POUTPUTs are used to generate the A, B, C, and D matrices for a mechanical system at an operating point. PINPUTs define the inputs to the system (plant) and POUTPUTs define the outputs from the system (plant). These can be accessed with function expression also, as shown in the example above. PINVAL(10,2) is the second element in the VARIABLES list for PINPUT/10 (that is, VARIABLE/22).
