ADAMS: terminate current step when passing through the same value as at t = 0

[jdox09]

Hi, an MSC.ADAMS beginner here.

I'm doing a design of experiments for various variables while studying a vertical DY deviation of a marker using a function measure:

DY(MARKER_RUN, MARKER_INIT)​

The coupler curves I am working with are convex curves and I want them to start and end at circa the same y-coordinate if possible within certain time range:

How do I set a sensor to terminate current step when the measure passes the initial value (meaning the same value of DY(MARKER_RUN, MARKER_INIT) as at t = 0.0 )? I'm opened to different approaches as well.

Thanks in advance.

Sorry I don't know how to it in View, but in your solver code (adm) you need a statement loosely based on the following

THE SENSOR STATEMENT HALTS THE SIMULATION IF THE
VEHICLE LONGITUDINAL VELOCITY DROPS BELOW 5.000000 MPH.

SENSOR/1000,VALUE= -2235.200000, GE,ERROR=0.001,HALT
, FUNC=IF(MODE-4:-1.0E+10,VX(5100,0100,5100),-1.0E+10)

A simpler option might be to add a test to your MOTION statement that is driving the rig - if t>1 and y>=y0 then motion =motion*0 sort of logic. Getting y0 might be an issue. This will freeze the mechanism and the sim continues until the end of the TIME statement.
