Hi,

 

I have a problem. I defined a spring type 4 with a force - displacement curve, where the spring ends move together. It works very well. Now I want to create a time-sensor, which should deactivate the spring after a time t=0.015 s from the beginning of the simulation. Could someone help me, please?

 

I have already defined a sensor type 0 with tdelay = 0.015 s and have referenced to the spring with lflag = 1, but it does not work.

I am using hyperworks 14.0 with radioss 14.0 as well. You can find my simple example model below.

    According to the doc : 
     
    For Sensor types SENS, AND, OR:
    •The sensor is activated after activation of sensor sens_ID1.
    •Minimum activation duration is given by Tdelay.
    •After Tdelay, sensor is deactivated if sens_ID2 is activated.
    •If sens_ID2 = 0, the sensor is deactivated after Tdelay.
