Comments

  1. Sensors can be used to activate airbags, imposed forces, pressures, and fixed velocities.
  2. Sensors can be used to activate or deactivate these elements: brick, quad, shell, truss, beam, spring or 3N Shell with /ACTIV.
  3. For Sensor types SENS:
    • 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.
